The National Command Authority includes which individuals besides the President?

• A. The Secretary of Defense and designated alternates.
• B. The Vice President and the Joint Chiefs.
• C. The Secretary of Defense only.
• D. The Speaker of the House.

Answer: (A)

The main idea here is who has the authority to order the use of nuclear weapons and how that authority stays reliable in a crisis. The National Command Authority is set up so a single, clear decision-maker can authorize a launch, with a built-in backup if that person is unavailable. Beyond the President, the group includes the Secretary of Defense and designated alternates who can step in to maintain command continuity. This arrangement ensures swift, decisive action without getting bogged down if the President can’t be reached. The other options include individuals or configurations not recognized as the standard NCA structure, whereas naming the Secretary of Defense plus the designated alternates captures the intended backup-and-continuity setup.
