The correct answer is option C, that is, carbon monoxide.
A combustion reaction takes place when a component reacts with oxygen and produces a huge amount of energy in the form of heat and light. A combustion reaction always exhibits oxygen as one reactant. The second reactant is always a hydrocarbon, that is, a compound formed of hydrogen and carbon. A combustion reaction always generates water and carbon dioxide.
The expected outcome would be A. The reaction will speed up after adding a catalyst to a chemical reaction.
