Which zone of the volleyball court is the 3-meter line located?

The correct choice identifies the 3-meter line as serving as a divider between the front row and back row on the volleyball court. This line is crucial because it defines an area that influences the rules surrounding player positions, particularly in relation to attacks and hitting the ball.

In volleyball, players in the back row must stay behind the 3-meter line when attempting to attack the ball. This regulation helps to maintain fairness and safety by ensuring that only front-row players, who are typically taller and positioned closer to the net, have the opportunity to perform attacks from the front row.

Knowing this, players need to be aware of their positioning concerning the 3-meter line, which directly impacts gameplay strategies, such as when a back-row player can jump and attack. This line is distinct from the service zone and the attack area, both of which serve different purposes in the structure of the game.
