Question

the greatest health risk factor which a person can control heredity inactivity cancer heart attack

Explanation:

To determine the greatest controllable health risk factor, we analyze each option:

• Heredity: Genetic factors, not controllable.
• Inactivity: Lack of physical activity, a lifestyle choice that can be controlled.
• Cancer: A disease, not a risk factor one controls directly (risk factors for cancer can be controlled, but cancer itself is not a risk factor).
• Heart attack: A medical event, not a risk factor one controls directly (risk factors for heart attack can be controlled, but the heart attack itself is not a risk factor).

Among these, inactivity is a modifiable (controllable) health risk factor.

B. Inactivity
