Which statement best describes the relationship between income and health?

• A. Health is unaffected by income
• B. Health worsens with higher income
• C. Health fluctuates randomly with income
• D. Health improves with higher income

Answer: (D)

Income is a major determinant of health: more income generally gives people better access to healthcare, nutritious food, safer housing, and healthier environments, while also reducing stress related to financial insecurity. These advantages tend to lead to better health outcomes, which is why the statement that health improves with higher income best describes the relationship. The other options contradict well-established patterns: health is not independent of income, it does not typically worsen with higher income, and the link is not random but shows a systematic association across populations.
