Quizplus · Accepted Answer

An antagonistic muscle is one that opposes or reverses the movement of another muscle. Therefore, the muscle that is antagonistic to a flexor muscle in the right arm would be an extensor muscle in the right arm. Option A and D are incorrect because they are both flexor muscles, and option B is incorrect because it refers to an extensor muscle in the left arm, which is not related to the right arm.
