Which of the following are listed as by-products of fire?

Explanation:
Fire produces energy as heat and creates smoke from the combustion process, and depending on the materials burning, it yields gases like carbon monoxide and carbon dioxide along with other toxic fumes. Oxygen isn’t a by-product of fire; it’s consumed during the burn. Water vapor is also produced, but the most complete and hazard-aware list a firefighter must recognize focuses on heat, smoke, and the toxic gases (CO, CO2, and other fumes). That makes the option that includes heat, smoke, CO, CO2, and other toxic fumes the best choice, because it covers the primary hazards firefighters must anticipate.
