Which of the following is a critical safety feature required in basements?

Emergency escape openings are critical safety features required in basements because they provide a means of escape in the event of an emergency, such as a fire. Building codes typically mandate that residential basements have at least one emergency escape and rescue opening to ensure occupants can exit safely if they are trapped. These openings can be a window or door that meets specific size and accessibility requirements, allowing individuals to quickly get outside if necessary.

While electrical outlets, carbon monoxide detectors, and fire extinguishers are important for safety in a home, they do not serve the same life-saving function as emergency escape openings in a basement scenario. Emergency escape openings are essential for ensuring an occupant's safety during life-threatening situations, which is why they hold such critical importance in basement safety features.
