Answer: (B)

The term 'fire barrier' refers to a construction assembly specifically designed to restrict the spread of fire, smoke, and heat between different spaces or areas in a building. This is crucial in maintaining the integrity and safety of structures during a fire incident, as fire barriers help contain the fire to the area of origin, thereby protecting occupants and allowing more time for evacuation and response. Fire barriers can consist of walls, floors, or ceilings that are constructed using fire-resistant materials, and they play a vital role in a building's overall fire protection strategy as outlined in fire codes and standards.

Understanding the role of fire barriers is important for comprehending building safety designs and fire prevention planning, as they serve a fundamental purpose in mitigating fire risks in various environments. This knowledge is vital for professionals involved in safety compliance, architecture, and construction.
