Answer:

Option C is the answer.

Explanation:

Your muscles need to tense up to pull your opponent toward your side, and contracting is how your arm generates the necessary force to pull the rope.

The answer to the question is: tighten and contract.
This is correct because muscle fibers must initially achieve a suitable length and tension, or "tighten," to enable muscle function. Once the muscle has tightened, it can then "contract," which reduces the angle of the joint through applied force. For instance, if the bicep in the arm is used to pull the rope, the angle between the forearm and the upper arm will diminish, consequently pulling the rope.
