C, A, or D depending on the direction of the acceleration vector.
Explanation:
Assumption: the man is facing forward.
If the train is increasing speed on a straight track, then C.
The reason is that he will speed up while the ball is in the air and therefore he will travel farther forward than the ball during that time.
If the train is decreasing speed on a straight track, then A.
If the train is going at constant speed on a curving track, then D.
I hope this helps,
