Solution

The principle of a soda fire extinguisher is A) Carbon dioxide produced cuts off the supply of oxygen by covering the fire like a blanket. This happens because when the extinguisher is activated, a reaction between baking soda (sodium bicarbonate) and an acid (usually sulfuric acid) takes place inside the extinguisher. This reaction produces a large amount of carbon dioxide gas very quickly. The carbon dioxide, being heavier than air, blankets the fire and cuts off the oxygen supply, thus extinguishing the fire.
