Answer 1

The correct option is D

All of the given options are right.

To start a fire we need a substance which can be burnt.

To start the burning process we need to supply the fuel with some heat.

And since burning is the chemical process of oxidation of the substance, oxygen is necessary for combustion to occur.

Hence all the three factors : air, fuel and heat are required to start a combustion process.
