Solution

The correct option is D Both Assertion and Reason are incorrect
Decomposition of $K C l O_{3}$ :
$2 K C l O_{3} ⟶ 2 K C l + 3 O_{2}$

Decomposition of $H g O$ :
$2 H g O ⟶ 2 H g + O_{2}$

From the above equations, equal no. of moles of $K C l O_{3}$ and $H g O$ produces different no. of moles of oxygen.

Since stoichiometry of reactants depends upon the balanced chemical equation.

Hence both Assertion and Reason are incorrect.
