Which of the following statements is true regarding fire regulations?

The statement that all buildings must comply with specified fire safety standards is accurate because fire regulations are designed to protect life and property from the dangers of fire, and these regulations typically apply to virtually all types of buildings, whether residential, commercial, or industrial. Ensuring compliance with these standards helps to establish a baseline of safety that mitigates risks associated with fire hazards.

Fire safety measures often include requirements for smoke alarms, fire exits, and fire-resistant materials, among other things, which are prescribed to ensure that even in the worst-case scenarios, occupants have a chance to escape safely and that the structure itself is less likely to contribute to the spread of fire.

The other options do not reflect the comprehensive approach of fire safety regulations. Fire safety measures are not optional, as they are mandated by law; not just public buildings are subject to these regulations, since residential buildings also have specific fire safety standards; and fire regulations are in effect at all times, not only during commercial hours, ensuring that safety is constant regardless of occupancy or use.
