Hint:This question gives the knowledge about the pollutants. Pollutants are defined as the unwanted substances which when come in contact with the atmosphere cause unwanted changes in the environment.

Complete answer:
The Non-biodegradable pollutants are the unwanted substances that can break down or get decomposed naturally and are very hazardous to the environment. Non-biodegradable pollutants do not get degraded very easily. Examples of non-biodegradable pollutants are synthetic fibres, DDT, insecticides, lead, mercury, arsenic, pesticides, polythene, plastics, silver foils and so forth.So, it is clearly evident that DDT is a non-biodegradable pollutant.

Therefore, option D is the correct.

Note:
Pollutants are defined as the unwanted substances which when come in contact with the atmosphere cause unwanted changes in the environment. Pollutants are of two types:
The types of pollutants are as follows:
A.. Biodegradable pollutants
B. Non-biodegradable pollutants
Biodegradable pollutants are the unwanted substances that can break naturally by the action of microorganisms and are not hazardous to the environment. Biodegradable pollutants get degraded very easily. Examples of biodegradable pollutants are cattle dung, urine, sewage, wool, leather, wood, paper, agricultural residues, animal bones and so forth.
Non-biodegradable pollutants are the unwanted substances that can break down or get decomposed naturally and are very hazardous to the environment. Non-biodegradable pollutants do not get degraded very easily. Examples of non-biodegradable pollutants are synthetic fibres, DDT, insecticides, lead, mercury, arsenic, pesticides, polythene, plastics, silver foils and so forth.
