Which government department is described as the principal agency for protecting the health of all Americans and providing essential human services?

• A. Centers for Disease Control and Prevention
• B. Department of Health and Human Services
• C. National Institutes of Health
• D. Food and Drug Administration

Answer: (B)

Recognizing which department leads federal health protection and essential human services. The Department of Health and Human Services is the principal government department charged with protecting the health of all Americans and delivering essential human services. It oversees major programs like Medicare and Medicaid and houses agencies that administer public health, childcare and family services, aging, and disability programs. While agencies such as the Centers for Disease Control and Prevention, the National Institutes of Health, and the Food and Drug Administration are important health-focused entities, they operate under this department rather than standing as the overarching agency themselves. So, this department best fits the description because it embodies the broad responsibility for health protection and comprehensive human services at the federal level.
