OK, you'd like some help.  Normally, I'd ask for a balanced chemical equation, to start with.  But since there are 4 possible choices, maybe you don't want to do all that work.  Since this question is multiple guess, can you try to exclude one, or narrow your choices down?  You want "most CO₂ per gram", so, which one is "biggest" or has the "most" of what CO₂ is made of?

You could start with at least the molecular formulas of the compounds...
