Which statement best reflects WHO's mission?

• A. To regulate healthcare globally.
• B. To promote market-based health solutions.
• C. To achieve universal access to care.
• D. Attainment by all people of the highest possible level of health.

Answer: (D)

WHO aims to ensure that everyone reaches the highest possible level of health. That exact framing—attainment by all people of the highest possible level of health—captures the broad, overarching goal of the organization: uplift health outcomes for all, not just provide care or regulate systems. The other ideas describe important activities or goals related to health, such as regulating services, promoting market approaches, or ensuring access to care, but they don’t state the full, universal objective that WHO itself uses as its mission.
