Final answer:

Preceding a static stretch with an isometric contraction of the muscle group to be stretched is called proprioceptive neuromuscular facilitation, is effective in improving muscle relaxation, and can activate the Golgi tendon organ.

The correct answer is options C

Step-by-step explanation:

Preceding a static stretch with an isometric contraction of the muscle group to be stretched does several things. This technique is called proprioceptive neuromuscular facilitation (PNF). It is indeed effective in improving muscle relaxation as it takes advantage of the neural reflexes that govern muscle control. Specifically, an isometric contraction can activate the Golgi tendon organ, which is a tension receptor that detects the force of muscle contractions and triggers a relaxation response to prevent muscle injury.

All of these outcomes work together to enhance the safety and effectiveness of stretching. Thus, c. All of these answers are correct applies as the statement includes proprioceptive neuromuscular facilitation, the improvement of muscle relaxation, and the activation of the Golgi tendon organ, following an isometric contraction prior to a static stretch.
