The limiting reactant in a reaction a. is the reactant for which there is the least amount in grams b. is the reactant which has the lowest coefficient in a balanced equation c. is the reactant for which there is the most amount in grams d. is the reactant for which there is the fewest number of moles e. none of the above

Actually the correct answer must be:

The limiting reactant in the reaction is the one which has the lowest ratio of moles available over coefficient in the balanced equation

This is because the actual mass or number of moles of the reactant does not directly dictate if it is a limiting reactant, this must be relative to the other reactants.

So the answer is:

e. none of the above
