Answer Details
The bone that articulates with the part labelled III is the femur.
The part labelled III is the acetabulum, which is a cup-shaped socket located on the lateral side of the pelvis. The femur is the thigh bone and is the longest and strongest bone in the human body. The head of the femur is shaped like a ball and articulates with the acetabulum to form the hip joint, which allows for a wide range of motion in the hip. Therefore, the femur is the bone that articulates with the part labelled III (acetabulum).
