Answer 1

Answer: (D)

Non-biodegradable pollutant

Answer 2

The correct option is option D, Non-biodegradable pollutant.

Non-biodegradable pollutants are those unwanted substances that can not be decomposed by bacteria. They are very hazardous to the environment. Examples of non-biodegradable pollutants are synthetic fibres, DDT, insecticides, lead, mercury, arsenic, pesticides, polythene, plastics, silver foils, and so forth. DDT is a non-biodegradable pollutant as till date there is no such enzyme found in any microbes that can degrade DDT.

Therefore, DDT is a non-biodegradable pollutant.
