A.
Move forward, and gradually stop moving.

B.
The ball will not move at all.

C.
The ball will continue to move forward with the same speed and direction.

D.

However, if you are able to throw the ball it would be answer C because there’s nothing acting on the ball to stop the motion. It depends on the context of the problem and which you think applies better
