The National Security Act of 1947 created several key structures. Which of the following was created?

• A. Central Intelligence Agency
• B. Federal Bureau of Investigation
• C. Department of Homeland Security
• D. National Security Agency

Answer: (A)

The act created a civilian foreign intelligence agency, the Central Intelligence Agency, to coordinate foreign intelligence gathering and analysis and to advise the President and the National Security Council. This established a centralized, civilian-led intelligence capability distinct from domestic law enforcement or military command, aligning postwar needs with civilian control of intelligence.

The FBI predates this act and handles domestic federal law enforcement and security investigations; the Department of Homeland Security was created in 2002 to unify border, immigration, and emergency response functions; the National Security Agency was established in 1952 for signals intelligence, evolving from earlier military programs, and not created by the 1947 act.
