उत्तर
This statement is True.
Explanation:
Carbon dioxide (CO2) is an excellent fire extinguisher because it works by displacing oxygen in the air, which is necessary for combustion. When CO2 is released on a fire, it reduces the oxygen level around the fire, effectively smothering it and preventing further burning. It is particularly useful for electrical fires and flammable liquids.
