Solution

The correct option is A True

Fire extinguisher contains sodium bicarbonate in water and sulphuric acid in a separate container inside it. When the fire extinguisher is released by pressing the knob on it, the sulphuric acid mixed with sodium bicarbonate solution producing a lot of carbon dioxide gas.

$2 N a H C O_{3} + H_{2} S O_{4} \to N a_{2} S O_{4} + 2 H_{2} O + 2 C O_{2}$
Carbon dioxide gas is neither combustible nor helps in combustion. It is heavier than air and offsthe supply of oxygen from air and hence removes the fire. So, sodium bicarbonate is used in fire extinguishers. So the given statement is true.
Hence option A is correct.
