What is the responsibility of the Secretary of the Air Force?

• A. To command all U.S. military forces.
• B. To oversee the Department of the Air Force and report to the Secretary of Defense.
• C. To regulate airspace and aviation safety standards.
• D. To supervise NASA's space exploration programs.

Answer: (B)

The question is testing who leads the Department of the Air Force and to whom that leader reports. The Secretary of the Air Force serves as the civilian head of the Department of the Air Force, responsible for organizing, training, and equipping the Air Force (and Space Force) and for setting policy and managing resources. Importantly, this position reports to the Secretary of Defense, not to a commander who directly controls all U.S. military forces. That broader command authority rests with the President and the combatant commanders.

Airspace regulation and aviation safety standards aren’t overseen by the Secretary of the Air Force; those functions come from civilian aviation authorities such as the FAA. NASA is a separate civilian space agency, not supervised by the Secretary of the Air Force, though it may coordinate with DoD on space matters.
