Solution
The correct option is DCO2 Photochemical smog is a type of air pollution formed through solar radiation reacting with airborne pollutants, like nitrogen oxides and volatile organic compounds. This type of air pollution is formed through the reaction of solar radiation with airborne pollutants like nitrogen oxides and volatile organic compounds. These compounds, which are called primary pollutants, are often introduced into the atmosphere through automobile emissions and industrial processes. Ultraviolet light can split nitrogen dioxide into nitric oxide and monatomic oxygen, 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.
