Answer:

A. Potential energy decreases and kinetic energy increases, but the total amount of mechanical energy remains the same.

Explanation:

Potential energy is the latent energy in an object at rest. Kinetic energy, is the energy expressed by an object in motion.

The ball is starting at rest and that is where the potential energy is at. In that case, the ball has no kinetic energy (no movement). When the ball begins to move that kinetic energy starts to increase and the potential energy decreases because it is no longer at rest.
