What should happen when a foul is committed during a throw-in and the thrower-in violates the throw-in procedure?

When a foul is committed during a throw-in and the throw-in procedure is violated, the proper action is to implement both the foul and the violation, which results in a change of possession.

In this situation, the foul takes precedence because it occurs during the throw-in phase. The significance of this is that the initial violation does not negate the effect of the foul. Therefore, the result is that the possession changes hands, with the team that was fouled being awarded the ball in a manner that typically follows standard procedures after a foul, unless specified otherwise by additional regulations in the game.

The process of having a throw-in slightly altered or voided is not the case here since the violation and the foul both influence possession rather than canceling each other out. In addition, ignoring either the foul or the violation would not reflect the structured rules of basketball that aim to ensure fair play and clarity in officiating. Thus, option C accurately describes the outcome of the scenario.
