The movement that brings a limb back towards the body in the frontal plane is known as adduction. This term specifically refers to the action of moving a body part closer to the midline of the body. For example, when you lower your arms back to your sides after raising them, you are performing adduction.

In contrast, the other movements mentioned have different definitions. Flexion involves decreasing the angle between two body parts, such as bending your elbow. Abduction is the opposite of adduction and refers to moving a limb away from the midline, like raising your arms sideways away from your body. Hyperextension involves extending a joint beyond its normal range of motion, which typically does not involve movement towards the body. Understanding these definitions clarifies why adduction is the correct choice for describing the movement of a limb returning to the body's midline in the frontal plane.
