text: economics help here....? the "law of supply" holds because as the price of a good increases, the opportunity cost of:  a) not producing the good increases b) producing the good decreases c) not producing the good decreases d) producing the good increases   please help if you can...thanks! a - the opportunity cost is defined as the value of the most valuable alternative.  assuming you are not currently producing the good, the opportunity cost of not producing that good increases as the price of the good increases.  oh yeah....i'm definitely 100% sure, just like the other guy....who was wrong!
