Final Answer :
E
Explanation :
A synergist is a muscle that contracts to assist the main muscle in performing a particular action. It works together with the agonist (main muscle) to produce the desired movement. The prime mover is also known as the agonist, the fixator stabilizes a joint, and the antagonist opposes the action of the agonist.
