Solution
The correct option is A Ozone, peroxyacetyl nitrate, aldehydes
Pollution is defined as addition of harmful components in the environment which alters the composition of an environment and that harmful component is known as pollutant. The reaction of solar radiation with primary airborne pollutants like nitrogen oxides and volatile organic compounds forms photochemical smog. Ultraviolet light can split nitrogen dioxide into nitric oxide and monatomic oxygen and this monatomic oxygen can then react with oxygen gas to form ozone. Products like ozone, aldehydes, and peroxyacetyl nitrates are called secondary pollutants. The mixture of these primary and secondary pollutants forms photochemical smog
So, the correct answer is 'Ozone, peroxyacetyl nitrate, aldehydes'
