Answer 1

The glenohumeral joint is more mobile, making it less stable. (Ans. C)

Step-by-step explanation:

Shoulder joint is composed of three bones shoulder blade (scapula), collarbone (clavicle), and upper arm bone (humerus) Shoulder joint or glenohumeral joint is classified as a socket joint and synovial ball structurally and functionally divides as a multiaxial joint and diarthrosis. Its helping in the articulation between the glenoid cavity present on the shoulder blade (scapula) and the upper arm bone (head of the humerus).

Because of the presence of very loose joint capsule that gives a limited interface of the scapula and humerus. So, it is known for the most mobile joint present in the human body.
