CaCO_3

Step-by-step explanation:

We are given that a chemical reaction

_
\implies CaO+CO_2

We have to find the value of reactant for given product.

Reactant: The substance on the left side in chemical reaction are called reactants.

Product: The substance on the right side in chemical reaction are called products.

In given product, there are calcium oxide and carbon dioxide.

Therefore, calcium, oxygen and carbon must be present in reactants.


CaCO_3\implies CaO+CO_2

Hence, option D is true.
