✓ Correct answer: C. KneeKnee is correct because this is the joint at which the movement predominantly occurs during the seated leg press exercise. The knee joint is the primary axis of rotation as the legs extend and flex during the motion, working primarily the quadriceps, hamstrings, and glutes. Hip is incorrect because it is not the primary axis in this movement, and shoulder is incorrect as it is not involved in the seated leg press exercise.
