(D) The catalytic oxidation of ammonia (Ostwald process) is represented by the reaction:$4NH_3 + 5O_2 \xrightarrow{Pt, 1100 \ K} 4NO + 6H_2O$The oxide formed is $NO$ (Nitric oxide).This $NO$ is further oxidized to $NO_2$ and then absorbed in water to produce $HNO_3$:$2NO + O_2 	o 2NO_2$$4NO_2 + 2H_2O + O_2 	o 4HNO_3$Thus,the oxide used in the preparation of $HNO_3$ is $NO$.

In the catalytic oxidation of ammonia,an oxide is formed which is used in the preparation of $HNO_3$. This oxide is
