Which of the following is a non-passenger category mentioned as requiring screening?

• A. Airline pilots
• B. Cabin crew
• C. Airline customer service personnel
• D. Passengers boarding

Answer: (C)

The main idea is that airport security screening isn’t limited to passengers; certain non-passenger personnel who need access to secure areas must also be screened. Airline customer service personnel fall into this category because they work in roles like check-in, gates, and baggage handling, and they routinely move through controlled zones where screening is required to prevent unwanted items and ensure identity verification.

Pilots and cabin crew are flight crew and follow security protocols specific to their roles, but the phrasing here points to a non-passenger staff category explicitly mentioned as needing screening, which is typically the airline customer service personnel. Passengers boarding are, by definition, passengers, not a non-passenger category.
