Which of the following refers to the cockpit of an aircraft?

The cockpit of an aircraft is commonly referred to as the flight deck. This term designates the area at the front of the aircraft where the pilots control the airplane. The flight deck is equipped with instruments and controls that enable pilots to navigate and operate the plane safely. Additionally, it serves as the workspace for the flight crew, where they can communicate with air traffic control and monitor various flight parameters.

Choosing this term is appropriate because "flight deck" specifically conveys the technical area where all critical operations related to piloting take place, distinguishing it from other parts of the aircraft. In contrast, the cabin refers to the area where passengers are seated, the control center typically involves broader operational oversight that may not be physically part of the aircraft, and air operations involves a range of activities related to managing flight schedules, logistics, and air traffic, rather than the physical space within the aircraft itself.
