Which bone provides the main structural support for the lower torso and connects to the legs?

• A. Rib Cage
• B. Patella
• C. Pelvis
• D. Coccyx

Answer: (C)

The pelvis functions as the main structural anchor for the lower torso and the bridge to the legs. It forms a sturdy ring at the base of the spine, supports weight from the upper body, and transfers that load into the femurs through the hip joints at the acetabulum. This setup allows the torso to stay supported while the legs move. The rib cage protects the thoracic organs and sits above the pelvis, not bearing the torso’s weight to the legs. The patella is a knee bone that aids in leg movement, not a central weight-bearing connector. The coccyx is a small tailbone with a limited role in supporting the body's weight.
