The correct set of species responsible for the photochemical smog...

Smog is derived from smoke $+$ fog, this is most common example of air pollution, photochemical smog occurs in warm, dry and sunny climate also known as oxidizing smog.
Unburnt hydrocarbons $+$ Nitric oxide
$N{O}_{2}\left(g\right)\overset{hν}{\to}NO\left(g\right) + O\left(g\right)$
${O}_{2}\left(g\right) + O\left(g\right) \to {O}_{3}\left(g\right)$
$C{H}_{4} + 2{O}_{3} \to \mathop{3C{H}_{2}O}_{\text{Formaldehyde}} + 3{H}_{2}O$
So the common component of photochemical smog are Ozone, No, acrolein, PAN, formaldehyde.
