Final answer:
The femur is the bone that is not part of the pelvic girdle; it is the thigh bone that attaches to the pelvis but is not a component of it.
Step-by-step explanation:
Among the choices listed, each of the following bones is part of the pelvic girdle except for the femur. Options A) ilium, B) ischium (ischiura typo), C) pubis, and D) os coxae (hip bone) are all components of the pelvic girdle. The ilium forms the superior part of the hip bone, and the hip bone itself consists of the ilium, ischium, and pubis - these three bones fuse together during late adolescence. The femur, on the other hand, is the thigh bone, which is the longest bone in the human body and articulates with the pelvis but is not a part of it.
