The correct answer is D. (The force of ball on bat and the force of the bat on ball.
Baseball is a game that we need to hit the ball using bat as hard as we can to make the ball fly as far as we can when other player will throw the ball as fast as possible to make it hard to hit.
The ball that pitcher throw has a velocity and acceleration. a ball with velocity will have some Force according to Newton's second Law. On the other side, batter will hit the ball using force from his swing. When the ball and the bat make contact, each force will negate each other. So, in order to make the ball fly high the batter need to give higher force than the force that the ball has.
Newton's Second Law tell us about that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the object’s mass.
From that statement we can conclude that the force of an object will get bigger when they move faster
