The trio of elements necessary for combustion is called the

Explanation:
Combustion needs three ingredients—heat to reach ignition, fuel to burn, and an oxidizer (usually oxygen) to sustain the reaction. The standard term for this grouping is the Fire Triangle. It helps explain why a fire stops if any one element is removed: cooling removes heat, starving removes fuel, and smothering removes the oxygen. The other terms aren’t used in fire science, so they don’t describe what must be present for combustion.
