• B. North American Sector
• C. National Aviation System
• D. Naval Air System

Answer: (A)

National Airspace System. In U.S. aviation this term refers to the integrated network of airspace, routes, facilities, and procedures that enable safe and efficient movement of aircraft. It includes controlled airspace, air traffic control centers and towers, communications, navigation aids, surveillance, weather services, and flight information services—together forming the system that manages how air traffic is flow-managed and separated. The other options aren’t the standard term used in this context: they refer to different concepts and aren’t the name of the system described.
