C Correct answer
Explanation

Ozone (O3) is produced as a secondary pollutant during photochemical smog formation when nitrogen oxides and volatile organic compounds react in the presence of sunlight. While nitrogen oxides are precursors, ozone is the end product formed. Hydrocarbons are VOCs that participate but aren't the final product, and methane is not directly involved in photochemical smog.
