Once the offensive wrestler has assumed a legal starting position, do they need to be stationary before the referee says "set"?

In wrestling, once the offensive wrestler has taken a legal starting position, they do not have to remain stationary before the referee instructs them to "set." This means that they can maintain their stance and be ready for the match to begin without being required to freeze. The act of being stationary before the command "set" could lead to an unnecessary delay and does not contribute to the functionality of the match’s beginning. This allows the wrestlers to demonstrate readiness and adjust their positions as necessary, facilitating a more dynamic start to the round.

The other options imply some form of restriction or requirement that doesn't align with wrestling's guidelines around starting positions. For example, the notion that wrestlers must be stationary or wait for a signal might lead to confusion or miscommunication during the initiation of the match. Understanding this concept is critical for both wrestlers and officials, ensuring the matches progress smoothly and efficiently.
