Solution

The correct option is D It is formed in stratosphere.
Photochemical smog is formed in troposphere not in stratosphere. It is produced in warm, dry and sunny climate. It's main constituents are $O_{3}, N O_{2}$ and unsaturated carbons. Ozone is formed due to reaction between $N O_{2}$ and atmospheric oxygen.
$N O_{2} (g) u v - \to N O (g) + O (g)$
$O (g) + O_{2} (g) \to O_{3} (g)$
