(c) The acceleration of both balls is the same.

Explanation:

Acceleration of any body freely falling is 9.81 m/s². The initial velocity of the body may be different but the acceleration is always constant.

Here, the second is thrown at a greater velocity than the first ball that is the only way the second ball can cross the first ball. The acceleration is constant so the initial velocity has to be different.

Hence, The acceleration of both balls is the same.
