Soot results from burning organic compounds. Soot is an example of

a. a primary pollutant

b. a secondary pollutant

C. a tertiary pollutant

d. none of the above

The correct option is a) a primary pollutant

Explanation:

A type of pollutant which is emitted directly from a source can be described as a primary pollutant.

Secondary pollutants can be described as pollutants which arise when primary pollutants react in the air.

A tertiary pollutant will arise from the primary and secondary pollutants.

In the scenario discussed in the question, soot is being formed as a pollutant by the direct burning of organic compounds. Hence, it is a primary pollutant.
