The clue that can be used to identify a chemical reaction as a combustion reaction from the options would be if a hydrocarbon reacts with oxygen.

Basically, a combustion reaction is a kind of reaction involving oxygen and another reactant with energy being released in the process. The energy is usually in the form of light and heat.

Thus, following the definition:

Oxygen is rather a reactant, and may not be a product in combustion reactions
Water reacting with carbon dioxide is not a combustion reaction
Reaction involving ions may not be a combustion reaction

The only reaction that may identify as a combustion reaction is, therefore, the one involving hydrocarbon and oxygen.
