Which of the following construction types uses materials that are designed to resist fire for extended periods?

The correct answer is fire-resistive construction. This construction type specifically utilizes materials intended to endure fire exposure for prolonged periods, thereby providing valuable time for occupants to evacuate and for firefighters to respond to the situation. Fire-resistive construction often includes elements such as reinforced concrete, masonry, and fire-rated assemblies that are engineered to slow the spread of fire and maintain the structural integrity of a building during a fire incident.

Fire-resistive materials are often tested and classified based on their ability to withstand heat and flame, ensuring that they can perform effectively under such conditions. This is particularly critical in multifamily dwellings, high-rise buildings, and commercial structures where the risks associated with fire can be greater.

Other construction types, such as ordinary and lightweight construction, may contain elements that can burn more quickly, increasing the overall fire load and allowing fire to spread rapidly. Noncombustible construction materials also play a role in mitigating fire risk, but they do not provide the same level of extended resistance to fire as fire-resistive construction does. Therefore, fire-resistive construction is the most suitable choice for resisting fire for an extended duration.
