What is the significance of the 'red and green' ankle bands?

The significance of the 'red and green' ankle bands is that they indicate the designated athlete in each match. In wrestling, each competitor is assigned a color to represent them during the match — red for one wrestler and green for the other. This system helps referees, officials, and spectators clearly identify the two participants, especially during scoring situations and when managing timeouts. This visual identification is crucial for ensuring that the match runs smoothly and that there is no confusion regarding which wrestler is which, particularly as the competition progresses and various calls and strategies are executed.

The other options, such as indicating weight classes or scoring positions, do not reflect the specific purpose of the ankle bands. Team identification is not the primary focus of the bands; instead, they serve to directly clarify each wrestler's identity within the context of the match.
