Limiting Reactants without a given mass

This is a question I have for Chemistry homework, but I don't understand how to solve it without a given mass. I narrowed the choices down (see below _) I know a limiting reactant well limits the reaction (so if there are 2 reactants) and the react left is the excess reactant.

I thought Propane would be the limiting reactant because the oxygen is in excess (though that was incorrect).

Then, I though Oxygen would be the limiting reactant (naturally) since its a combustion reaction (though that is incorrect).

Determine whether each reaction depends on a limiting reactant. Explain why or why not and identify the limiting reactant. (Select all that apply.)

(c) Propane (C3H8) burns in excess oxygen to produce carbon dioxide and water.

Yes, one reactant is naturally limiting. Yes, there are two reactants. No, all reactants are in excess. No, there is only one reactant. propane oxygen carbon dioxide water Not enough information to identify which is the limiting reactant.
