Justification: Option B: Carbon dioxide (CO2) is the best extinguisher.
One way to get CO2 is to release a lot of dry powder of chemicals like
sodium bicarbonate (baking soda) or potassium bicarbonate. Near the
fire, these chemicals give off CO2. Hence, B is the most appropriate
option.
Option C: Saltpetre is a material used in making explosives, so clearly C
is incorrect.
Option D: Acetylene is a flammable gas and will only increase the fire
hazard. So, D is wrong.
