Pectoral Girdles -
Each pectoral girdle consists of two bones: 1 clavicle and 1 scapula.
The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and seventh ribs.
The dorsal, flat, triangular body of the scapula has a slightly elevated ridge called the spine which projects as a flat, expanded process called the acromion.
The clavicle articulates with the acromion.
Below the acromion is a depression called the glenoid cavity which articulates with the head of the humerus to form the shoulder joint.
Each clavicle is a long slender bone with two curvatures.
This bone is commonly called the collarbone.
Hence, the correct option is c pectoral girdle of mammals
