Who must be behind the free-throw line during a free throw?

During a free throw, the proper positioning of players is critical for the flow of the game. The correct answer highlights that only those players not occupying a marked lane space must remain behind the free-throw line. This is essential because it allows the shooter to have a clear and unobstructed opportunity to attempt their shot.

The rules dictate that players from both teams have designated areas during a free throw; those players in lane spaces, which are the marked areas closest to the basket, may position themselves near the basket and are allowed to enter the lane immediately after the ball is released by the shooter. Conversely, all other players, including those not involved in the action at the free throw line, must maintain their position behind the line until the free throw is taken. This rule helps to prevent any unfair advantage or interference during the shooting attempt, maintaining the integrity of the free throw process.
