It can't be A because you need to balance the equation to get the correct amount of moles. It can't be B because that is what you are attempting to find out. It can't be C because you need to use this step to find the answer to the question. Through the process of elimination you can determine that you do not need to use step D. Also the question does not specify any form of volume, mL, or L, etc. Hope this helps! :)
