The international health organization sponsored by the United Nations is:

• A. World Health Organization
• B. National Institutes of Health
• C. Centers for Disease Control and Prevention
• D. Occupational Safety and Health Administration

Answer: (A)

The main idea here is identifying which organization operates globally under the United Nations to lead health efforts. The World Health Organization is the UN’s specialized agency for health, established to coordinate international health work, respond to global health emergencies, set international health standards, and provide guidance that countries use to protect and improve health worldwide. That international scope and UN affiliation make it the organization described.

The other bodies are national agencies based in the United States with different roles. The NIH is the U.S. National Institutes of Health, focused on biomedical research within the United States. The CDC is the Centers for Disease Control and Prevention, primarily concerned with disease prevention and control within the U.S. The OSHA is the Occupational Safety and Health Administration, dealing with workplace safety in the U.S. None of these are international organizations sponsored by the United Nations.
