Vedclass · Answer

(D) Photochemical smog is a grey or yellow-brown opaque smog that creates an oxidizing environment. It primarily contains secondary pollutants or photochemical oxidants. Key components formed during its production include nitrogen dioxide $(NO_2)$,ozone $(O_3)$,and peroxyacyl nitrates $(PAN)$. Carbon dioxide $(CO_2)$ is a greenhouse gas and a primary pollutant,but it is not a component of photochemical smog. Therefore,the correct answer is $CO_2$.
