The correct answer is C: Exerts a force on the bat equal to the force the bat exerts on the ball.

This arises from the Newton's 3rd Law of motion:  When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
