A is correct.

Simple machines help you do work. Work is given by the amount of force times distance over which it is applied (W=Fd). Simple machines are great because they reduce the amount of FORCE you need to use to accomplish the same task, making it easier on you. However, they must output the same amount of WORK in order to accomplish this task, so by W=Fd, the d must increase if F decreases in order for W to stay the same!
