Solution

The correct option is C sodium bicarbonate
Soda acid fire extinguishers contain sulphuric acid and sodium bicarbonate. Both of these chemicals are present in two different sealed flasks inside the extinguisher. In case of emergency, the seal is broken, and sulphuric acid and sodium bicarbonate react instantly to give $C O_{2}$ . The $C O_{2}$ gas released put off the fire. Hence the correct option is B.
