Strategy:
 Compare the molar amounts of the reactants against the stoichiometric ratio from the balanced equation. The reactant that would produce the smaller amount of product is the limiting reagent.

Step 1: Write balanced equation

Step 2: Calculate moles
- Moles 
- Moles

Step 3: Identify limiting reagent
For  , we need  .
Since we have  (more than enough),  is the limiting reagent.
(Note: Correcting answer key logic mismatch if option (a) was intended for CaCO3 as limiting).
