What is the term for the rapid oxidation of combustible material accompanied by a release of heat, light, smoke and toxic gases?

Explanation:
Fire is the rapid oxidation of combustible material in the presence of an oxidizer, releasing heat and energy as visible flames, along with smoke and gases. This description matches what you see in a growing blaze: heat and light are produced, flames appear, and combustion gases—often including toxic components—are generated. The other terms refer to different states or are not technical descriptors: an incipient stage is the early ignition phase, smoldering is a slow, flameless combustion that mainly produces smoke, and the word common isn’t a fire-science term. So the best answer is fire.
