Which department is described as America's #1 government agency by personnel size?

• A. The Department of Defense
• B. The Department of the Army
• C. The Department of Homeland Security
• D. The Central Intelligence Agency

Answer: (A)

The main idea here is recognizing which federal department employs the most people. The Department of Defense has by far the largest workforce, including active-duty service members across the Army, Navy, Air Force, and Marines, plus a vast civilian staff and reserve components tied to the department. No other department comes close in total personnel, and the Army is a branch under DoD rather than its own separate department. Homeland Security and the CIA have far smaller staffs. So the department with the biggest headcount is the Department of Defense.
