Scoliosis is characterized by abnormal lateral curvature of the spine.

• A. Scoliosis
• B. Hypertension
• C. Angina
• D. Coronary artery disease

Answer: (A)

Scoliosis is defined by a sideways (lateral) curvature of the spine, which can sometimes be accompanied by a rib bump on one side and a slight rotation of the vertebrae. This description matches the statement, confirming why scoliosis is the term used for this condition. The other options describe heart and blood vessel problems—hypertension is high blood pressure, angina is chest pain from reduced blood flow to the heart, and coronary artery disease is narrowed or blocked coronary arteries—so they do not refer to spinal curvature.
