Which bone is a bone of the rib cage?

• A. Ribs
• B. Scapula
• C. Mandible
• D. Cranium

Answer: (A)

Understanding the rib cage involves recognizing which bones form its protective frame. The ribs are the bones that create the thoracic cage, curving around the chest and attaching to the spine in back and often to the sternum in front. This structure protects the heart and lungs and assists breathing as the chest expands and contracts. The other bones listed serve different regions: the scapula is part of the shoulder girdle, the mandible is the lower jaw, and the cranium is the skull enclosing the brain. So, the ribs belong to the rib cage.
