Correct Answer: Carbon dioxide
Solution : The correct option is Carbon dioxide.
Carbon dioxide (CO 2 ) is a popular fire-extinguishing gas. Carbon dioxide suppresses flames by displacing oxygen, one of the basic components required for combustion. When carbon dioxide enters a fire, it decreases the oxygen concentration in the immediate vicinity, smothering the flames and stopping further combustion. This approach is very effective for putting out flames in small places, electrical fires, and fires involving flammable liquids.
