Which of the following is the most anterior portion of the hip bone?

A) Ischium
B) Ilium
C) Acetabulum
D) Pubis
E) Ischial tuberosity

The pubis is the most anterior portion of the hip bone. It forms the anterior portion of the "socket" of the hip joint (the acetabulum) and articulates with the pubic bone of the opposite hip at the pubic symphysis. The ilium is the largest portion of the hip bone and forms the uppermost part of the hip bone, while the ischium is the lowermost portion and forms the bony prominence upon which we sit (the ischial tuberosity). The acetabulum is a cup-shaped depression on the lateral surface of the hip bone where the head of the femur articulates.
