The insertion of Rhomboid Major is on which bone?

Explanation:
The key idea is where the Rhomboid Major attaches to bone. It inserts on the medial (vertebral) border of the scapula, from about the spine to the inferior angle. This placement lets the muscle pull the scapula inward (retract) and help rotate the scapula to stabilize the shoulder girdle against the thorax. The other bones listed aren’t insertion points for this muscle—clavicle, humerus, and sternum—so the scapula is the correct bone where the Rhomboid Major attaches.
