1. The area in an aircraft where the pilot and co-pilot sit to control the flight is commonly known as the cockpit.
2. Another term used to refer to the cockpit is the Flight Deck. This term is widely used in aviation to describe the area where the pilots operate the aircraft.
3. The Flight Deck houses the controls, instruments, and communication equipment necessary for flying the plane.

So, in the context of an aircraft, the Cockpit is also known as the Flight Deck, making option B the correct answer.
