There are choices for this question namely:
<span>a. ilium
b. pubis
c. ischium
d. sacrum
</span>
The correct answer is the "ilium". The pelvis is composed of 3 bones that fuse to make the pelvic girdle (with the sacrum). These bones are the ilium, ischium, and the pubis. The ilium forms the superior border of the pelvis, the ischium is the inferior, the pubis is the anterior, and the sacrum is the posterior. Attached is an image of the pelvic girdle, not that the ilium is at the superior portion of the pelvis.
