Identify the reactants and products

\[
\text{Reactants: } \text{CH}_4 \text{ (hydrocarbon)} + \text{O}_2 \text{ (oxygen)}
\]
\[
\text{Products: } \text{CO}_2 \text{ (carbon dioxide)} + \text{H}_2\text{O} \text{ (water)}
\]

Classify the reaction type

\[
\text{Hydrocarbon} + \text{O}_2
ightarrow \text{CO}_2 + \text{H}_2\text{O} \implies \text{Combustion reaction}
\]

Match with the given options

\[
\text{Option D corresponds to combustion.}
\]
