Which of the following best defines "Cabin" crew?

The term "cabin crew" best refers to the individuals who ensure passenger safety and comfort during a flight. This includes flight attendants who are trained to manage various aspects of the passenger experience, from conducting safety demonstrations and leading emergency procedures to serving food and beverages. Their primary role is to create a safe and pleasant environment for all passengers throughout the flight.

In contrast, those responsible for aircraft maintenance focus on the technical aspects of ensuring the airplane's airworthiness, while individuals who operate navigation equipment play a critical role in flight management and navigation, which is distinct from the cabin experience. Managing the flight's fuel efficiency falls under the purview of flight operations and engineering teams, not the cabin crew. Therefore, identifying cabin crew correctly highlights their specific responsibilities and functions within the airline industry.
