Final answer:
A fire in the operating room requires fuel, oxidizer, and ignition source.
Step-by-step explanation:
The correct answer is D) Fuel, oxidizer, and ignition source.
A fire in the operating room requires three components: fuel, oxidizer, and ignition source. Fuel is any kind of combustible material, while an oxidizer is a substance that provides oxygen to support the combustion process. An ignition source is responsible for the initial ignition of the fire.
For example, in a match, the matchstick (fuel) is ignited by friction from striking it against a rough surface (ignition source). The match head contains chemicals that react with oxygen from the air (oxidizer), allowing the fire to start and continue burning.
