A. 
Ball A and Ball B would hit the ground at the same time.

Answer:

A.   Ball A and Ball B would hit the ground at the same time.

Explanation:

If we ignore the effects of friction only gravity affects the drop of the balls; in this case, mass does not affect the speed of falling objects. This result was demonstrated by Galileo Galilei.
