Solution

The correct option is A $N O, N O_{2}$
Nitric oxide is a colorless, flammable gas with a slight odor. Nitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. When $N O$ comes in contact with air it oxidizes and following reaction takes place.
$2 N O + O_{2} ⟶ 2 N O_{2}$
Hence, 'x' is $N O$ and 'y' is ${N O}_{2}$ .
