What requirement must be met when executing a move element change of edge in Group B?

When executing a move element change of edge in Group B, the requirement that must be met is that the skater must remain on the same foot before and after the change of edge. This is crucial as it demonstrates the skater's ability to maintain control and balance throughout the maneuver. The successful execution of a change of edge involves executing the transition smoothly while adhering to the principles of edge control.

Remaining on the same foot emphasizes the importance of stability and the technique involved in the transition. Skaters need to show proficiency in managing their weight shift and edge changes without introducing any additional support or reliance on changing feet.

In this context, other options do not align with the fundamental principles governing the execution of this particular move element. Allowing a change of foot, permitting additional steps, or requiring a change in position are not consistent with the technical requirements for a proper change of edge in this scenario, which focuses specifically on maintaining a single-foot position during the transition.
