The therapeutic advantage that pencillin V has over
pencillin G is:: (A) More reliable oral absorption, (B) Greater resistance to pencillinase, (C) Slower renal excretion, (D) Broader antibacterial spectrum
Answer is A. ACID-RESISTANT  ALTERNATIVE  TO PENICILLIN-G 
Phenoxymethyl penicillin (Penicillin V) 
It differs from PnG only in that it is acid stable. Oral absorption is better; peak blood level is reached in 1 hour and plasma  t½  is 30-60 minutes.
The antibacterial spectrum of penicillin V is identical to PnG, but it is about 1/5 as active against Neisseria, other gram negative bacteria and anaerobes.
