b. a secondary pollutant
c. a tertiary pollutant
d. none of the above
Acid rain is an example of a secondary pollutant. Therefore, option (B) is correct.
Factory, car, and power plant emissions are primary pollutants. Primary pollutants include and NOx from fossil fuel combustion.
Secondary pollutants are created by chemical interactions between main pollutants and other air components. Acid rain is created when primary pollutants like sulphur dioxide (SO2) and nitrogen oxides (NOx) mix with water, oxygen, and other atmospheric components. These interactions produce sulfuric and nitric acids, which fall as acid rain. Therefore, option (B) is correct.

Answer:
The Great Plains
Explanation:
Hot air has a much lower density than cold air and for this reason, the large plains would be ideal for an industrial city if the goal is to have fewer air pollution incidents related to temperature inversions. This is because if the large plains are lower, soon the hot air will rise while the cold air will tend to go down.
In short, within the great plains the hot air being less dense rises, in contrast, the cold air (more dense) descends, forming the convection currents.
