An acromion process is characteristically found in the

  1. pelvic girdle of mammals
  2. pectoral girdle of mammals
  3. skull of frog

Answer

(2) pectoral girdle of mammals

Solution

As per NCERT, each half of the pectoral girdle consists of a clavicle and a scapula.

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.

∴ The acromion process is found in the pectoral girdle of mammals.
