• A. (a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)
• B. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
• C. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
• D. (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)

Answer 1

The correct option is B (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

(a) There are 12 pairs of ribs. Each rib is a thin flat bone connected dorsally to the vertebral column and ventrally to the sternum. The last two pairs (${11}^{\mathrm{th}}\mathrm{and}{12}^{\mathrm{th}}$) of ribs are not connected ventrally and are therefore, called floating ribs.

(b) & (c) 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 (collar bone) articulates with this.

(d) Below the acromion process is a depression called the glenoid cavity which articulates with the head of the humerus to form the shoulder joint.
