What are the four primary components of the Fire Triangle?

The correct answer identifies the three essential components that must be present for combustion to occur, which are heat, fuel, and oxygen.

Heat is necessary to raise the material to its ignition temperature. Fuel refers to any combustible material, including solids, liquids, or gases that can burn. Oxygen, usually from the air, is required to sustain the combustion process. When these three elements are combined in the right conditions, a fire can ignite and continue to burn.

The other options include additional elements or incorrect combinations that do not align with the fundamental understanding of fire chemistry. For example, while pressure can influence combustion, it is not one of the primary components of the fire triangle. Similarly, light and smoke are products of combustion rather than necessary elements for it to start and continue.
