A non-controllable risk factor for coronary heart disease

• A. Heredity
• B. Diet
• C. Smoking
• D. Physical Inactivity

Answer: (A)

Heredity is the correct choice because it reflects genetic factors you inherit, which you cannot change. This makes it a non-modifiable risk factor for coronary heart disease. In contrast, diet, smoking, and physical inactivity are behaviors you can modify to reduce risk—improving heart health through healthier eating, quitting smoking, and increasing physical activity. Knowing about a family history can guide proactive screening and prevention, but the genetic predisposition itself cannot be altered.
