What is the name of the one-step kick technique in Korean martial arts?

The correct choice refers to the term "Il so sik," which translates to "one-step kick" in Korean martial arts. This technique is fundamental in various martial arts styles, particularly in taekwondo and hapkido, as it emphasizes the importance of precision, control, and timing in executing a kick.

In "Il so sik," practitioners often start from a basic stance and practice executing a kick towards an opponent in a controlled manner, focusing on proper form and technique. This one-step approach allows students to concentrate on their balance, the trajectory of the kick, and the mechanics involved, thereby reinforcing foundational skills crucial for their martial arts development.

The other terms, while possibly related to different techniques or concepts within Korean martial arts, do not refer specifically to the one-step kick technique, which emphasizes its distinctiveness and importance in training.
