Correct answer is I and III only . 

After performing the "hold-relax with agonist contraction" PNF stretch for the hamstrings, the resulting increase in flexibility .

 autogenic inhibition  

reciprocal inhibion 

PNF stretching allows for relaxation of the stretched muscle by stimulating ,  When golgi tendon receptors are stimulated, they cause inhibition of the muscle being stretched, leading to greater relaxation of the muscle.
