Which of the following techniques is a method for deflecting or redirecting an impending strike?

The technique that involves deflecting or redirecting an impending strike is best represented by blocks. Blocks are defensive maneuvers used to intercept or deflect an incoming attack, enabling an individual to protect themselves while maintaining the opportunity to counter or respond effectively. This technique does not necessarily involve physical control of the opponent's body, unlike joint locks or restraints, which focus more on control or manipulation rather than simply intercepting an attack.

While a choke hold can incapacitate an opponent, it does not serve the purpose of redirecting a strike. Joint locks require engagement with the opponent and are generally used to control their movements rather than simply defend against an attack. Restraint techniques are designed for controlling a person after a confrontation rather than for actively defending against an incoming strike. Therefore, blocks are specifically designed for the purpose of deflecting or redirecting strikes, making them the correct choice in this context.
