Which of the following is listed as a genetic or physiological risk factor?

• A. Mental illness
• B. Sunbathing
• C. Regular exercise
• D. Balanced diet

Answer: (A)

Mental illness can have genetic and physiological underpinnings, meaning there are inherited factors and biological processes that influence a person’s susceptibility to health problems. This fits as a genetic/physiological risk factor because it reflects biology rather than just behavior or environment. In contrast, sunbathing is an environmental exposure, and regular exercise or a balanced diet are protective lifestyle factors that reduce risk rather than representing an inherent biological predisposition.
