Sodium Hydrogen carbonate or Sodium Bicarbonate is used in making Soda-acid fire extinguishers. (Option 1 is correct)

It is the best fire douser for home use.
It can be made manually or even on large scale in factories.
The fire quencher contains sodium bicarbonate in water along with sulfuric acid in a different container.
By turning the handle on it, the sulphuric acid reacts with the sodium bicarbonate and creates a little measure of carbon dioxide gas.
It is heavier than air and thus removes the oxygen supply to the air, extinguishing the blazes.
The reaction: 2NaHCO₃ + H₂SO₄ → Na₂SO₄ + 2H₂O + 2CO₂
