Final Answer :
E
Explanation :
The median and radial nerves innervate most of the muscles that move the forearm and hand. The musculocutaneous nerve innervates part of the biceps brachii muscle, while the ulnar and axillary nerves innervate muscles in the hand and upper arm respectively, but not as extensively as the median and radial nerves. The suprascapular nerve innervates the supraspinatus and infraspinatus muscles of the shoulder.
