The United States Department of Defense is charged with coordinating and supervising all agencies and functions of the government concerned directly with national security and the United States Armed Forces. Which department is this?

• A. Department of Defense
• B. National Institutes of Health
• C. Health Promotion
• D. Health and Human Services

Answer: (A)

This item tests your knowledge of which federal department handles national security and the military. The description points to the United States Department of Defense, which is charged with coordinating and supervising all agencies and functions concerned directly with national security and the U.S. Armed Forces. It oversees the Army, Navy, Air Force, Marines, and other defense components, led by the Secretary of Defense, who advises the President on defense policy and military operations. The other options don’t fit this role: the National Institutes of Health is a biomedical research agency under Health and Human Services; Health Promotion is not a standalone department; and Health and Human Services focuses on public health and welfare rather than national defense.
