Answer:
Each pectoral girdle is formed of two halves. Each half of pectoral girdle consists of a clavicle and a scapula.
The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and the seventh ribs.
The dorsal, flat, triangular body of scapula has a slightly elevated ridge called the spine which projects as a flat, expanded process called the acromion. The clavicle articulates with this.
Below the acromion is a depression called the glenoid cavity which articulates with the head of the humerus to form the shoulder joint. Hence scapula extends between second and seventh ribs.
So, the correct answer is 'Second and seventh ribs'.
