In a volleyball match, can a player contact the ball on the opponent’s side of the net legally?

In volleyball, a player can legally contact the ball on the opponent's side of the net, but this is limited to specific situations. The correct choice states that this is permissible only with a legal block.

A legal block involves the defensive attempt to prevent the ball from crossing the net by reaching over to intercept the attack. When a player goes up to block, they are allowed to extend their hands over the net into the opponent's space as long as they do not interfere with the opponent's ability to play the ball. This action is strategic and essential within the rules of the game, as it is a part of defensive plays.

In contrast, contacting the ball on the opponent's side in any other context, such as attempting to hit or play a ball that is attacked by an opponent without being in the blocking position, is not allowed. This ensures fairness, giving both teams the right to play the ball without interference. Thus, understanding the rules surrounding blocking and contacting the ball over the net is essential for effective training and officiating in volleyball.
