Vedclass · Answer

(B) The correct answer is $B$. Photochemical smog is primarily composed of nitrogen oxides $(NO_x)$,volatile organic compounds $(VOCs)$,and ozone $(O_3)$,which are formed by the action of sunlight on these precursors. It does not contain $SO_2$ as a primary component; $SO_2$ is associated with classical smog (sulfurous smog). Option $A$ is correct as catalytic converters reduce $NO_x$ emissions. Option $C$ is correct as $CFCs$ are responsible for ozone depletion. Option $D$ is correct as acid rain increases the solubility of heavy metals in water pipes.
