Which bone is a component of the pelvic girdle?

• A. Ilium
• B. Clavicle
• C. Femur
• D. Radius

Answer: (A)

The pelvic girdle is formed by the hip bones, each composed of the ilium, ischium, and pubis. Among the options, the ilium is the bone that belongs to this girdle; it makes up the upper, blade-like part of the hip bone and helps form the acetabulum, the socket for the femur. The clavicle belongs to the shoulder girdle, while the femur and radius are parts of the lower limb and upper limb, respectively. So the ilium is the correct component of the pelvic girdle.
