Exothermic reaction
Explanation:
when methane (natural gas) reacts with oxygen, the result is carbon di-oxide and water, along with heat, hence making it an exothermic reaction.

The answer to the question is c. I and II.
The reaction which releases energy and the overall enthalpy change of the reaction is negative is known as an exothermic reaction.
The burning of methane releases energy in the form of heat, and the enthalpy change is negative.
Hence, it is an exothermic reaction.
A chemical reaction usually involving atmospheric oxygen and the release of energy is called a combustion reaction.
Hence, the burning of methane is a combustion reaction.
