Acid rain is an example of **b. a secondary pollutant**.

Secondary pollutants are not emitted directly into the atmosphere but are formed through chemical reactions between primary pollutants and other substances in the atmosphere. In this case, sulfur dioxide and nitrogen dioxide react to form acids that contribute to acid rain.
