the correct answer is Sulphuric acid is non flammable so soda acid is most common fire extinguisher. Carbon dioxide is liberated by the action of sulphuric acid on baking soda or sodium bicarbonate. This increases the percentage of carbon dioxide in air. Due to this the supply of air is cut off and fire is extinguished.
