What happens if B1 violates during A1's unsuccessful free throw attempt?

When a violation occurs during a free throw attempt, such as a player from the opposing team (B1) acting inappropriately, the rules dictate a specific action. In this instance, the correct answer indicates that a substitute throw is awarded to the offensive team (team A).

This is in accordance with NFHS rules, where if a violation is committed by a player of the opposing team (in this case, B1), the free throw attempt is nullified, and the shooting team is given another opportunity to execute the free throw. This ensures fairness by allowing team A to shoot again due to the obstruction caused by the violation of team B.

The rationale behind awarding a substitute throw serves to penalize the violating player, providing an opportunity for the offensive team to capitalize on their chance to score points without interference. Such a rule reinforces the importance of adhering to the game's regulations, maintaining the flow and integrity of play.
