Final answer:
A volley is the tennis shot used to hit the ball before it touches the ground, which can be performed using either a forehand or backhand grip. Thus, options A and B are correct.
Step-by-step explanation:
The tennis shot used to return the ball before it bounces on the ground is the volley. In a volley, the player hits the ball while it is still in the air without letting it bounce. This shot requires quick reflexes and good hand-eye coordination. It is commonly used in doubles play and close-range situations near the net.
The tennis shot used to return the ball before it bounces on the ground is called a volley. Neither a forehand nor a backhand directly answers the question, as these terms refer to the way the racket is held and the side of the body from which the ball is struck during various shots, including volleys, groundstrokes, and serves. A volley can be executed with either a forehand or backhand grip, depending on the position and approach of the ball.
Thus, options A and B are correct.
