How should the assistant referee assist the referee when observing illegal holds?

The assistant referee plays a crucial role in ensuring that the match is conducted fairly and within the rules. When observing illegal holds, the assistant referee should signal and inform the referee promptly. This collaboration is essential because the referee is the one who makes the final decision regarding any infractions, but they may not always have a complete view of the action on the mat.

By signaling, the assistant referee can draw attention to the illegal hold without disrupting the flow of the match excessively, allowing the situation to be addressed quickly and appropriately. This cooperative approach helps maintain the integrity of the competition and protect the wrestlers from harm caused by illegal maneuvers.

The other options do not support the proper conduct of the match. Taking over the match would undermine the authority of the main referee, ignoring the situation could lead to serious consequences for the wrestlers, and discussing it with the audience does not contribute to resolving the issue within the match itself and can create distractions.
