What should a referee do if a wrestler is close to the edge of the mat?

The correct choice emphasizes the referee's responsibility to carefully assess the situation when a wrestler approaches the edge of the mat. Evaluating the circumstances before deciding allows the referee to ensure the safety of the wrestlers, as actions near the edge can lead to potential hazards such as falling off the mat or injury. The referee's role includes making informed decisions that respect the flow of the match while prioritizing the well-being of the participants.

By observing the wrestlers' positioning and actions, the referee can determine whether it is necessary to stop the match or allow it to continue. This thoughtful approach helps maintain a controlled environment and assures that competitive integrity is upheld.

The other options fall short of this careful assessment. Ignoring the action or continuing without interruption could lead to dangerous situations that they are uniquely trained to prevent. Calling for a timeout immediately might not always be necessary, especially if the action is ongoing and manageable. Therefore, evaluating the situation embodies the balanced and prudent approach required in wrestling officiating.
