Which of the following is one of the five tenets of Tae Kwon Do?

Integrity is one of the five tenets of Tae Kwon Do and holds a significant role in the martial art's philosophy. It emphasizes the importance of honesty and moral principles as a foundation for character development. Practicing integrity involves being truthful in one's actions and interactions, both in and out of the dojang (training hall). This tenet encourages practitioners to uphold their values and commitments, making it essential not only for personal growth but also for fostering respect within the martial arts community.

The other tenets, while important qualities, do not represent the official tenets of Tae Kwon Do. Benevolence relates to kindness and compassion, which are virtues of a good martial artist but not recognized as a core tenet. Persistence reflects the spirit to keep training and improving, a valuable trait, yet it falls under determination rather than a primary tenet. Strength is a physical attribute that can aid in martial arts practice, but it is not a philosophical principle that guides behavior.
