Which of the following is NOT a type of striking technique mentioned?

The choice of C as the answer highlights the distinction between established striking techniques and movements that are not typically recognized as striking techniques within martial arts or self-defense training. A knee strike, backfist strike, and front kick are all recognized techniques used to strike an opponent effectively, targeting various parts of the body for maximum impact.

The knee strike involves driving the knee upward into an opponent, often aimed at the midsection or head. The backfist strike utilizes the back of the fist to hit an opponent quickly, typically aimed at the head or face. The front kick, a powerful and direct technique, involves kicking forward with the front of the foot, aimed at the opponent's torso or head.

In contrast, the elbow twist does not represent a conventional striking technique. Instead, it might suggest a movement involving the elbow joint but lacks the characteristics of an actual strike aimed at an opponent. This distinction is essential for understanding the terminology and techniques employed in striking disciplines.
