The function of an Overhead Bin (OHB) in an aircraft is to provide enclosed storage for passengers. These bins are typically located above passenger seats and are designed to hold carry-on luggage and personal items during the flight. This improves cabin organization and passenger comfort by keeping the aisles and seating areas clear of baggage.

While the other options relate to different aspects of aircraft operations, they do not align with the intended purpose of an OHB. Monitoring cabin temperature typically falls under the responsibilities of the flight crew and is managed through the aircraft's environmental control systems. Cooking areas, such as galleys, are designated spaces for food preparation and are usually found in a separate section of the aircraft, away from passenger seating. Emergency equipment is stored in specific compartments and locations designed for safety and quick access, not within the overhead bins intended for passenger storage. Therefore, with the focus on passenger convenience and space management, the primary function of an OHB is indeed to provide enclosed storage for passengers.
