xenn [34]

Answer:

B. When the racket hits the tennis ball with a force, the tennis ball applies an equal but opposite force to the racket.

So, when the force is applied by the racket on the ball then the ball also applies an equal intensity of force in the opposite direction on the racket. It is just that the the force on the racket is absorbed by the player holding it.
