The correct option is A Antagonistic muscles

Antagonistic muscles are the types of muscles that opposes the action of another which means one relax and the other contracts. Triceps and biceps are examples of antagonistic muscles because in order to conduct a back and forth movement, the biceps contracts to lift the forearm while the triceps relax to support the biceps' contractions.
