a. cool the burning substance

b. supply the fire oxygene

c. remove the fuel from the fire

d. add sand to the fire

I would like to know which answer is the correct one

Answer 1

The fire will burn faster if Oxygen is added. Fire relies on three components, heat, fuel and oxygen. Increasing any one of these will increase the rate of combustion.

Answer 2

oxygen fuels the fire. that's why you're told not to run when you get you clothes on fire. If you're talking about like a campfire, then just gently blow on it to give it oxygen.
