What are common safety features seen in the cabin of an aircraft?

The correct answer highlights the essential safety features that are critical for passenger safety in an aircraft cabin. Emergency exits, along with their marked signage, are crucial for swift evacuation in case of an emergency. Seat belts are fundamental safety devices that help to secure passengers in their seats during turbulence or emergencies, thereby minimizing the risk of injury. Illuminated escape path indicators provide guidance to passengers on the fastest route to exits, especially in low visibility conditions or in the event of smoke. These safety features are designed to ensure that passengers can evacuate quickly and safely if necessary, reflecting a priority on safety and security within the cabin environment.

Other options, while they may contribute to passenger comfort and convenience, do not serve a direct role in meeting safety regulations or protocols, emphasizing that safety is paramount in the design and operation of aircraft.
