The burning of methane is an example of both an exothermic reaction and a combustion reaction.

An exothermic reaction is a chemical reaction that releases energy by light or heat. The burning of methane releases heat, thus it is an exothermic reaction.

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Methane (CH4) reacts with oxygen to produce carbon dioxide and water, releasing energy in the process. Therefore, it is also a combustion reaction.

A decomposition reaction is a reaction in which a single compound breaks down into two or more elements or new compounds. The burning of methane does not fit this definition.

So, the correct answer is c. I and II.
