Is the official correct in ruling a violation when A-2 does not position their foot correctly in the free throw lane?

The correct choice is based on the fundamental rules governing player positioning during free throws in basketball. Proper positioning is crucial for maintaining the integrity of the game, and it is emphasized that all players in the free throw lane must follow specific guidelines.

When a player (A-2 in this case) does not position their foot correctly in the lane, it violates the established rules that dictate how players must stand during a free throw attempt. These rules ensure fairness and order on the court. By requiring players to maintain proper positioning, officials help to prevent potential advantages or disadvantages that could arise if players were allowed to line up haphazardly.

This ruling reflects the necessity for all players—both the free throw shooter and those in the lane—to abide by the regulations, thereby supporting a fair competitive environment. The violation is not limited to just the free thrower; it encompasses all players involved in the play. This understanding reinforces the importance of the rules set forth by the governing bodies of the sport, highlighting that adherence to positioning is indeed mandatory to ensure proper and fair gameplay.
