For making a fire you need 3 things:
-Fuel
-Heat or Ignition
-Oxygen

A fire is actually something that reacts with oxygen. The reactant is the fuel which reacts with oxygen, and the heat or ignition is what initiates the reaction.
Carbon Dioxide is a common product of this reactions, not a key component. So the correct answer is B
