Final Answer :
B
Explanation :
The scapula (shoulder blade) is a bone on the back side of the shoulder where many muscles of the arm have their origin. Examples of such muscles are the deltoid, rotator cuff muscles, and biceps brachii. The humerus (upper arm bone) serves as the attachment site for many of these same muscles' insertions.
