Answer #1

Ans- (a) Movement of the eyeball

Explanation-

The abducens nerve controls the movement of the lateral rectus muscles in humans. This muscle is responsible for outward gaze. A damage to the peripheral part of the abducens nerve causes double vission due to an unopposed action of the medial rectus muscles hence causing the affected eye to look towards the midline.The image describes an injury to the abducens nerve.
