Final answer:
Photochemical smog is a type of air pollution caused by the reaction of solar radiation with nitrogen oxides (NOx) and volatile organic compounds (VOCs) emitted from the combustion products of automobiles.
Step-by-step explanation:
Photochemical smog is a type of air pollution caused by the reaction of solar radiation with nitrogen oxides (NOx) and volatile organic compounds (VOCs) emitted from the combustion products of automobiles. This reaction leads to the formation of a brown haze above cities. Therefore, the statement 'Photochemical smog results from the interaction of sunlight with the combustion products of automobiles' is True.
