Moving arm towards the body’s midline–

Correct option is C

Sol. Adduction is the movement of a body part towards the body’s midline. For example, lowering your raised arm back to your side or moving your legs inward toward each other are adduction movements. This action is the opposite of abduction, which moves the body part away from the midline. Adduction is important for coordinated motion and maintaining posture and balance.
Explanation of each option:
· (a) Abduction – Incorrect. Abduction is the movement away from the midline. Lifting the arm sideways is an example of abduction.
· (b) Flexion – Incorrect. Flexion refers to bending a joint, like bending the elbow or knee, and is not related to movement toward or away from the midline.
· (c) Adduction – Correct. Adduction moves a limb toward the midline of the body. It is a key movement in activities like walking, swimming, and posture maintenance.
· (d) Extension – Incorrect. Extension is the straightening of a joint, such as straightening the elbow or knee after flexion. It does not indicate directional movement toward the midline.
