Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
If reactants and products are found in two or more phases, the equilibria describing them is called heterogeneous equilibrium. In heterogeneous solutions, the molarity of solids and liquids remain constant throughout the reaction, which means their value can be denoted as 1.
Thus equilibrium (given below) attained in a closed vessel remains unaltered by the addition of $C a C O_{3} (s)$ because heterogenous reaction is unaffected by solid and liquid.
$C a C O_{3} (s) ⇌ C a O (s) + C O_{2} (g) ↑$
Option A is correct.
