How is atmospheric oxygen availability related to fire events?
Answer and explanation
Correct answer: Oxygen makes combustion possible and higher availability can intensify burning
Combustion requires three components: fuel, heat, and an oxidising agent, usually oxygen. Oxygen is not ordinarily the fuel, but it allows the fuel to react and release heat. If the oxygen supply increases, burning may become faster and more intense; reducing oxygen helps extinguish fire. Thus option A correctly explains the relationship, while B, C, and D contradict the fire triangle.
