Which factor best explains variation in health outcomes beyond individual biology?

• A. Genetic ancestry is the sole determinant.
• B. Personal attitude alone determines health outcomes.
• C. Access to healthcare, social inclusion, and policy environment.
• D. Biological variation among populations has no impact on health.

Answer: (C)

Health outcomes are shaped more by social context and systems than by biology alone. The best answer points to how people actually access care, how included they feel in their communities, and the policies that shape health opportunities. Access to healthcare affects prevention, timely diagnosis, and treatment; social inclusion reduces stress and builds support networks that improve wellbeing; and the policy environment determines funding, coverage, and protections that create or hinder healthy living. These social determinants explain why health varies across groups beyond individual biology.

Statements that focus only on genetics, personal attitude, or claim that biological variation has no impact miss how much health is driven by social and structural factors that shape everyday choices, opportunities, and care.
