Hint-To solve this problem firstly we will learn about the fire extinguisher, its working principle, the reaction occurring inside it. We will study all the information related to it and by using this information we can easily approach our answer, so let's study them in brief.
Complete step by step solution:
> The fire extinguisher is used to control fire, the concept of the fire triangle for the generation of fire, we need three things to be present simultaneously. These are fuel, a heat source and air. If we remove any one of these resources, the fire can be controlled easily. Fire extinguishers are generally used to cut off the supply of oxygen, by which we can easily control fire.
> It works on the principle based on the following three conditions:
Cooling, combustible material below its ignition temperature
Cutting off, air supply
Cooling, combustible material simultaneously while cutting off the air supply.
> Soda acid for extinguishers consists of sodium hydrogen carbonate and sulphuric acid. The reaction happening between Sodium bicarbonate solution and sulphuric acid exert pressurized water onto a fire.
$2NaHC{O_3} + {H_2}S{O_4} \to N{a_2}S{O_4} + 2{H_2}O + 2C{O_2}$
So, the correct answer is option B.
Note - Soda acid fire extinguisher having sodium bicarbonate and sulphuric acid. It contains an iron vessel with a side discharge nozzle. The iron vessel is packed with sodium bicarbonate solution. Sulphuric acid is held up in a small glass bottle and is kept inside the iron vessel, the knob fixed just above this bottle, the acid bottle breaks open into the sodium bicarbonate solution. This bust open sulphuric acid reacts with sodium bicarbonate to form sodium sulphate, water and carbon dioxide.
