When does the jurisdiction of the referee begin?

The correct response is that the jurisdiction of the referee begins when they arrive at the competition site. This signifies that the referee's authority and responsibility to enforce the laws of the game start as soon as they arrive at the location where the match will take place.

This jurisdiction encompasses various responsibilities, including addressing pre-game issues, ensuring that the playing field and equipment are in accordance with regulations, and overseeing the teams' behavior before, during, and after the match. It is crucial for referees to establish their presence and authority early on to ensure a smooth and fair match.

The incorrect options refer to significant moments but do not accurately reflect the entirety of a referee's role. The start of the game or when teams are ready only marks specific points during which the referee’s authority is exercised, but their responsibility begins well before those moments. Additionally, entering the locker room does not fully encapsulate the scope of their jurisdiction, which extends beyond that private setting to encompass the entire competition environment.
