The pelvis is comprised of three main bones that fuse together during development: the ilium, ischium, and pubis. These three bones form one complete hip bone on each side of the pelvis, which then connects at the front via the pubic symphysis and at the back to the sacrum, which is part of the vertebral column but not counted as a part of the pelvic bones themselves.

The reasoning for selecting three as the correct answer is based on the standard anatomical classification of the pelvis. Beginners may be confused because they might think of the entire pelvic area, which could include the sacrum and coccyx, but they are separate structures and not counted as part of the pelvic bones themselves. Understanding this distinction is essential for grasping basic human skeletal anatomy, particularly in contexts such as midwifery, where knowledge of pelvic structure is pertinent to childbirth and maternal health.
