Correct Answer:
(A) I-Band Contracts

Explanation:
The gluteus maximus is one of the major involved muscles of the low-bar back squat exercise. As the upward phase is performed, the muscle is engaged in “concentric” muscle action. The muscle contracts during concentric muscle action, therefore the I-Band within the sarcomere contracts as well.
