The cabin is primarily designed for which of the following?

The cabin of an aircraft is primarily designed to carry passengers and crew, providing them with a safe and comfortable environment during the flight. This includes seating arrangements, overhead storage for personal items, and various safety features specifically tailored for passenger welfare. The layout of the cabin is aimed at maximizing passenger comfort and convenience, with features like restrooms, cabin crew workspaces, and emergency exits designed with the needs of passengers in mind.

While cargo, baggage, and catering are also important functions within an aircraft, they are not the primary purpose of the cabin space. The cargo and baggage areas are typically located in separate compartments, and although there are provisions for catering, like galley space, these are secondary to the main function of carrying people. As a result, the design and configuration of the cabin are oriented chiefly toward accommodating passengers and crew members.
