Answer: C) Combustion reaction.

Explanation: a combustion reaction is an exothermic reaction in which something reacts with oxygen. The combustion of organic compounds usually takes the form: organic compound + oxygen => water + carbon dioxide. As we can see the given reaction is an organic compound (C2H6) plus oxygen (O2) and the products are carbon dioxide (CO2) and water (H2O), so it is a combustion reaction.
