✅ Before You Answer

• Verify which term is actually used with the phrase fire tetrahedron in basic firefighting manuals. • Check that the option you select refers to a continuing combustion process, not just heat transfer or a device like a flare. • Make sure the term you choose is a standard firefighting concept, not an unusual or unfamiliar phrase.
