The broad, upper part of the hip bone, one of three bones that fuse together to form the pelvis.
Acetabulum
The Acetabulum is the concave surface of the pelvis that receives the head of the femur, forming the hip joint.

Final Answer :
B
Explanation :
The acetabulum is formed by the parts of the ilium, ischium, and pubis. It is a deep socket that articulates with the head of the femur to form the hip joint. The obturator foramen is formed by the ischium and pubis, and is a passageway for nerves and blood vessels. The pubic arch is formed by the pubic bones and is wider in females than in males. The greater sciatic notch is a notch formed by the ilium and ischium, and allows for passage of the sciatic nerve. The iliac fossa is a large, concave area on the ilium that forms part of the pelvic cavity.
