Solution

The correct option is A Ball and socket
Each scapula or pectoral girdle has a concave, articular surface called the glenoid cavity which articulates with the head of the humerus. The ball like the head of the humerus articulates with the glenoid cavity which creates a ball and socket joint that allows the upper limb great motility. So, the correct answer is 'Ball and socket'.
