Answer: D

Explanation: B and C are irrelevant in this context, there is no reason to consider them. The answer is D as if the ball pushes the bat left, the bat pushes back on it in the opposite direction (to the right)

Consider the interaction between a baseball bat and a baseball. The baseball forces the bat to the left; the bat forces the baseball to the right.

Answer: Option D

Step-by-step explanation:

This is purely an example of Newton's third law. As per Newton's third laws, for each and every action, there exists a magnitude equal and directed-opposite force, called reaction. But, the action and reaction appear on different objects.

So, hence when the ball hits the bat to the left, it inducts some force onto it, and the same force is imposed by the bat on the ball towards the right. It will be in the opposite direction. The ball moves with more velocity than the bat, because i.e. till the ball's mass is much smaller than the bat, it gets more velocity.
