Solution

The correct option is D All of the above
Bringing the temperature below the ignition point ensures that no combustion-related hazard occurs as the fuel cannot catch fire below the ignition point. Water forms a layer and removes air(oxygen) from the fire triangle by acting as an insulator of air.
