Which of the following includes creating compartments within a building with fire-resistive walls?

The correct choice involves containment, which focuses on creating compartments within a building to prevent the spread of fire and smoke. Fire-resistive walls are integral to this practice as they help to contain flames and limit the damage during a fire incident. By establishing compartments, the integrity of the building is maintained, and the safety of occupants is enhanced, allowing them more time to evacuate and reducing the potential for extensive damage.

In comparison, fire suppression refers to systems and methods designed to extinguish or reduce the intensity of a fire, often involving water, foam, or fire extinguishers. Evacuation pertains to the process of safely leaving a building in the event of an emergency. Fire alarm systems are designed to detect smoke or fire and alert occupants to danger, initiating evacuation procedures. While all these aspects are critical components of fire safety and management, the specific creation of fire-resistive walls distinctly falls under the definitions of containment practices, making it the correct choice in this context.
