What elements are required for combustion?

Explanation:
Combustion needs three things at once: a fuel, an oxidizer (usually oxygen in the air), and enough heat to start and keep the reaction going. That trio is why this question points to the combination of fuel, oxygen, and heat. Water isn't a fuel and can't support burning; it actually helps extinguish flames by cooling and displacing oxygen. Electricity can provide heat, but it isn’t itself one of the essential elements that must be present for burning to occur. Without heat, the fuel and oxygen can’t reach the activation energy to ignite. So the best choice includes all three necessary components: fuel, oxygen, and heat.
