Which of the following is a way to bow respectfully in martial arts?

The practice of bowing respectfully in martial arts is an important tradition that signifies respect towards instructors, fellow practitioners, and the art itself. "Sabum-Nim Kae Dehayo Kyung Rye" translates to "I bow to my teacher," which clearly reflects the practice of showing reverence and acknowledging the authority and knowledge of a teacher. This phrase is particularly appropriate in the context of martial arts where respect and hierarchy play significant roles.

Understanding the nuances of bowing in martial arts goes beyond the physical act—it embodies the spirit and culture inherent in such practices. The other options, while they have significance in martial arts, pertain to expressions of gratitude or respect in different contexts. For instance, "Kook Ki Eh Dehayo Kyung Rye" refers more broadly to bowing to the country or the nation, and "Gamsa Hapnida" means "thank you." "Kwan Chang Nim Kae Dehayo Kyung Rye" acknowledges a higher-ranking official or master but does not specifically denote a bow directed towards a teacher in a training setting, making the first choice the most fitting for respectful bowing in martial arts.
