Answer 1

The correct option is A Pelvic girdle

• Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones i.e each half of pelvic girdle is made up of ilium, ischium, and pubis.
  
• At the point of fusion of the ilium, ischium and pubis bones there is a cavity called acetabulum to which the thigh bone(femur) articulates. Hence acetabulum is a part of the pelvic girdle.
• So, the correct answer is 'Pelvic girdle'.
