The Contract-Relax Stretching Technique Applies the Principle of Reciprocal Inhibition

The contract-relax stretching technique applies the principle of reciprocal inhibition. Which of the following BEST defines this principle?

A) Activation of muscles on both sides of a joint simultaneously will cause an overflow cascade of muscle recruitment
B) Activation of muscles on both sides of the body simultaneously will cause an overflow cascade of muscle recruitment
C) Activation of a muscle on one side of a joint will cause inhibition of the muscle on the opposite side of the joint
D) Activation of a muscle on one side of the body will cause inhibition of the same muscle on the opposite side of the body
