What technique includes both abduction and adduction to bring fins together during a kick?

The frog kick is characterized by its unique movement pattern that involves both abduction and adduction of the legs. This motion allows the diver to draw their fins together effectively during the kick. In the frog kick, the legs are initially spread apart (abduction), and then the diver brings the fins back together through adduction as they complete the stroke, providing propulsion and stability. This technique is particularly useful in cavern diving, where maintaining control and minimizing disturbance in the water is crucial. Additionally, the frog kick helps in maximizing efficiency, allowing the diver to move smoothly and with minimal effort, which is essential in confined spaces. The distinct combination of abduction and adduction in the frog kick makes it the correct answer to the question posed.
