Verified step by step guidance

Step 1: Begin by understanding the anatomy of the pelvis, which is composed of four main bones: the sacrum, ilium, ischium, and pubis.

Step 2: Learn the function and location of each bone. The sacrum is a triangular bone at the base of the spine, the ilium forms the upper part of the pelvis, the pubis is located at the front, and the ischium forms the lower and back part of the pelvis.

Step 3: Focus on the ischium, which is the bone that supports the body when sitting. It has a specific structure called the ischial tuberosity, which is the part of the bone that bears weight during sitting.

Step 4: Compare the ischium to the other bones listed in the question. The sacrum is part of the spine, the ilium is higher up and does not bear weight directly during sitting, and the pubis is located at the front and does not provide support for sitting.

Step 5: Conclude that the ischium, specifically the ischial tuberosity, is the correct answer because it is the part of the pelvis designed to bear weight when sitting.
