How many skaters must execute a feature simultaneously in a choreographic requirement?

The requirement for the performance of a choreographic feature in synchro skating is that a specified number of skaters must execute the feature simultaneously, as outlined in the technical rules. This emphasizes the importance of teamwork and synchronization within the group, which are fundamental aspects of synchro skating. By stating "the required number of skaters," the answer acknowledges that each choreographic element has specific criteria that dictate how many skaters need to be involved in order to fulfill the requirement effectively.

This focus on a defined number of skaters ensures that the performance reflects the team's cohesion and creativity, as they must work together to present the choreography as intended. It also highlights how the complexity of the feature can vary depending on what is called for in the requirements, making it clear that successful execution depends on meeting these established guidelines.

In contrast, the other options suggest either insufficient participation (like one or two skaters) or an unrealistic expectation that all skaters must perform together, which does not account for the diversity of choreographic features and their requirements in synchro skating.
