Final answer:

The dynamic stabilizers of the glenohumeral joint are the rotator cuff muscles: supraspinatus, infraspinatus, teres minor, and subscapularis, which serve as dynamic ligaments providing joint support.The correct option is C.

Step-by-step explanation:

The dynamic stabilizers of the glenohumeral joint are primarily provided by the four rotator cuff muscles: supraspinatus, infraspinatus, teres minor, and subscapularis.

These rotator cuff muscles not only facilitate various movements of the upper limb but also serve to hold the head of the humerus in position within the glenoid cavity.

Thus, they function as 'dynamic ligaments' that provide the primary structural support for the glenohumeral joint.The correct option is C.
