Answer:

D

Explanation:

Arm internal rotation

Internal (medial) rotation represents the movement of the humerus when an arm flexed to 90° at the elbow is rotated around the longitudinal plane of the humerus such that the hand moves towards the midline of the body. The degree of rotation is dependent on the degree of abduction.
