Can nonjumpers break the plane of the center-restraining circle during the jump ball toss?

During a jump ball toss, the rules state that only the jumpers designated for the jump ball are allowed to occupy the area within the center restraining circle. Nonjumpers must remain outside of this area until the ball has been tossed and has cleared the plane of the circle. This regulation ensures that the jumpers have an unobstructed opportunity to compete for the ball.

If nonjumpers were allowed to break the plane of the center restraining circle during the jump ball, it could lead to interference, unfair advantages, or confusion as they could potentially disrupt the fair contest between the two jumpers. Maintaining this boundary is crucial for the integrity of the jump ball situation, and therefore, the correct answer affirms that nonjumpers cannot enter this area until the jump ball is completed.
