Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Hydrogen peroxide is thermodynamically unstable and decomposes to form water and oxygen.

$H_{2} {1 - O}_{2} \to H_{2} 2 - O + \frac{1}{2} {0 O}_{2}$

Hence, option $A$ is correct.
