<passage>:
Earth set itself grimly to meet them with corrosive fire, determined to blast them back to the stars. But they erred in thinking hush, and the ship jarred slightly as a thunderbolt slammed vengefully into its field. Behind him somebody made a choked noise, the only sound in the stunned "Suppose we settle this argument about humanity," said Knof Llud Quest III , as for forty hours the ship had decelerated. Quest III the of Llud's, nine hundred years ago.... He growled, "What happened to Quest III's crew. It was a subdued excitement men and women, they the same racial characteristics possessed by those aboard the Quest III in the ship and had never seen a planet. The grownups talked in low voices, in tones of mingled eagerness and apprehension, of what might Quest III was coming home the lie at the long journey's end. For the Quest III's captain, came slowly down the narrow stair from the observatory, into the big rotunda that was now the main out from its original cramped quarters. Now the interstellar ship was little more than a hollow shell. Eyes lifted from the vision screens to interrogate Knof Llud have happened to Earth? After all, it's only been nine hundred years." There's a new course to be set now—for Earth." Sun, mirrored and multiplied by the screens. In that light Lesra's eyes gleamed with unshed tears. Captain Llud found Navigator Gwar Den looking as smug as the cat that ate the canary. Gwar Den was finding that the actual observed positions of the planets thus far located agreed quite closely with Earth. Llud nodded curt approval, remarking, "Probably we'll be intercepted Quests returned successful, or if they returned at all. And we don't know what changes have taken place on Earth. It's possible—not likely, though—that something has happened to break notify him as soon as Earth's surface features became clear Lesra and the children—but somehow he didn't want to do that either. He felt empty, drained—like his ship. As the Quest III's fuel stores and the hope of success in man's mightiest venture had dwindled, so the Quest III in interstellar flight while years and decades had raced by on the home world. Procyon had possessed a habitable planet, we could have returned after we cannot betray the plan.... This may be man's last chance of escaping his pitiful limitation to one world in all the Universe. Certainly the building of this ship . Perhaps our effort will prove as futile as pyramid-building, less practical than orgies of slaughter to reduce pressure.... In any case, it would be impossible to transport very many people to other stars "Hopeless, unless we find planets!" Earth. Now we turn back along a curve that will take us past many more perhaps the human race itself, would have perished from memory. "That was why the planners limited our voyage, and those of the other phase, and before we can get back it may have collapsed completely from was once 'home' has probably been swept away.... "It doesn't matter. Today I gave orders to swing the ship." Savagely Knof Llud stabbed the button that shut off the speaker. Then Llud sighed. He still couldn't say just why he had given the order to to falter one moment in flight. The captain was on his feet instantly, but then his movements became such collisions were rare to the vanishing point. No harm could have been done. The Quest III's collision armor was nonmaterial and for practical purposes invulnerable. the vessel. Llud snatched up the receiver with the speed of a scalded cat. "Captain?" It was Gwar Den's voice, stammering a little. "Captain, we're being attacked!" short buzzes and repeat, ringing through all the great length of the interstellar ship. Knowing that Gwar Den was still there, he said, "Now—attacked by what?" "Ships," said Gwar Den helplessly. "Five of them so far. No, there's a sixth now." Repeated blows quivered the Quest III's framework. The navigator said, obviously striving for calm, "They're light craft, not Llud hesitated, said, "All right. Come along and keep out of the way." He headed for the bridge with strides that the boy could not match. There were people running in the corridors, heading for their posts. Their faces were set, scared, uncomprehending. The Quest III shuddered, again and again, under blows that must have had millions of horsepower behind them but it plunged on toward Earth, its mighty engines still steadily braking its interstellar velocity. To a man, the ship's responsible officers were already on the bridge, his father. "If they had anything heavier," surmised the captain, "they'd have unlimbered it by now. They're out to get us. But at this rate, they can't touch us as long as our power lasts—or until they bring up some bigger stuff." the Quest III's shell was doing it at velocities where the distinction between matter and radiation practically ceases to exist. the ship forces impinging on the outside of the field were similarly transmitted and rendered harmless. The effect was as if the vessel and all space inside its field were a single perfectly elastic body. A meteoroid, for example, on striking it rebounded—usually vaporized by the impact—and the ship, in obedience to the law of equal and opposite Quest III would have felt nothing at all of the vicious onslaught being hurled against them, save that their wait for us. But why on Earth—" "That," said the captain grimly, "is what we have to find out. Why—on Earth. At least, I suspect the answer's there." Quest III bored steadily on through space, decelerating. Even if one were no fatalist, there seemed no reason to stop decelerating or change course. There was nowhere else to go and too little fuel left always attacking, with the senseless fury of maddened hornets. The interstellar ship bore no offensive weapons—but suddenly on one of the Quest III's bridge looked questions at each other, as the thought of help from outside flashed into many minds at once. But Captain Llud said soberly, "It must have Quest III , except that they were rocket-propelled and of far lesser size. Their Quests might have encountered and been traced home by some unhuman race that was greedy and able to constant arrival of fresh attackers, while others raced away into space, presumably returning to base to replenish their ammunition. That argued a planned and prepared interception with virulent hatred behind it. Elsuz Llug, the gravitic engineer, calculated dismally, "At the rate hours." "We'll have reached Earth before then," Gwar Den said hopefully. "If they don't bring out the heavy artillery first." "We're under the psychological disadvantage," said the captain, "of not Smiles splintered the ice of tension. Captain Llud said, "Maybe you've repeating on each the same brief recorded message: "Who are you? What do you want? We are the interstellar expedition Quest III ...." And so on, identifying themselves and protesting that they were unarmed and peaceful, that there must be some mistake, and There was no answer. The ship drove on, its fuel trickling away under multiplied demands. Those outside were squandering vastly greater amounts of energy in the effort to batter down its defenses, but III's ponderous and unswerving progress toward Earth had somehow frightened it. So it was trying to frighten them.

<question>:
What would've happened if Captain Llud tried to turn around and change course from Earth?

<options>:
A They probably would've been shot at and the passengers would've died eventually with low resources.
B They would've tricked one of the ships into housing all of the passengers and flying home on that ship instead of the Quest III ship.
C They would've been left alone by the Earthen ships and accepted once they discussed matters some more.
D The Earthen ships would've trapped and invaded the Quest III ship and held the passengers hostage.

<answer>:

A
