Which set correctly lists the three elements of the fire triangle?

• A. Oxygen, Combustible Material (fuel), Heat
• B. Water, Oxygen, Soil
• C. Heat, Pressure, Water
• D. Fuel, Gravity, Cold

Answer: (A)

Fire needs three elements to start and keep burning: heat, fuel, and oxygen. Heat raises the fuel to its ignition temperature and sustains the chemical reaction. Fuel is the material that burns. Oxygen supports the oxidation process that drives combustion. Remove any one of these and the fire cannot continue. The set that lists oxygen, fuel, and heat matches these three essential elements exactly. The other sets introduce items that aren’t part of the triad—water, soil, gravity, or cold—which may influence a fire but aren’t the fundamental components that make fire possible.
