Solution

The correct option is A $O_{3}$ will oxidize $H_{2} O_{2}$ into $O_{2}$
The oxidation state of oxygen in hydrogen peroxide and molecular oxygen is different. Hence, the reaction involving hydrogen peroxide and oxygen is a redox reaction in which hydrogen peroxide is oxidized to molecular oxygen. This reaction is facilitated by ozone which is a strong oxidizing agent.
