Solution

The correct option is A $O_{3}$
Photochemical smog formed by action of sunlight on
unsaturated hydrocarbons and nitrogen oxides.
Nitrogen oxides split into nitric oxide and nascent oxygen.
$N O_{2} (g) h ν \to N O (g) + O (g)$
Nascent oxygen forms ozone.
$O (g) + O_{2} (g) ⇌ O_{3} (g)$

So, the correct answer is $^{'} O_{3}^{'}$
