Which bone is known as the back bone?

• A. Pelvis
• B. Cranium
• C. Scapula
• D. Spine

Answer: (D)

The main idea is recognizing that the backbone is the central supporting column of the body. The spine, made of vertebrae stacked along the back, provides structural support, protects the spinal cord, and acts as the axis for posture and movement. It runs from the skull down to the pelvis and includes regions like cervical, thoracic, and lumbar. The other parts listed have different roles: the pelvis forms the hip region and supports weight of the lower body, the cranium is the skull that protects the brain, and the scapula is the shoulder blade. So the spine is the correct term for the back bone.
