From my own point of view, the answer is D. This is because when calcium oxide is produced, the mole ratio between it and calcium carbonate is 1:1, as such we need the molar mass of calcium carbonate to get its moles used and also the molar mass of calcium oxide to calculate its mass produced after obtaining the moles.
