**Core Concept**
The rotator cuff is a group of muscles and tendons that surround the shoulder joint, providing stability and facilitating movement. It is composed of four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis.

**Why the Correct Answer is Right**
The correct answer is formed by the supraspinatus, infraspinatus, teres minor, and subscapularis muscles. These muscles work together to provide a wide range of motion to the shoulder joint, including flexion, extension, abduction, and rotation. The supraspinatus muscle is responsible for the initial stages of abduction, while the infraspinatus and teres minor muscles assist in external rotation. The subscapularis muscle, on the other hand, contributes to internal rotation and stabilization of the shoulder joint.
