when i made more research concerning this question i found out that Hydrogen peroxide is an oxidizing agent but in the presence of a stronger oxidizing agent like concentrated HNO3, it acts as a reducing agent and itself transformed into an oxygen gas ie changing the oxidation state of oxygen from -1 in H2O2 to zero in O2 [D]

a reducing agent gets oxidised in all the equations h2O2 was reduced to water except D making it correct

The answer provided is not even an equation of a reaction! How can that be correct?
