Solution
The correct option is D Air, water and soil
Dichlorodiphenyltrichloroethane (DDT) was widely used as an insecticide. However, its usage resulted in the widespread pollution of air, water and soil. DDT is a stable compound but it evaporates very easily and mixes with the atmosphere to become an air pollutant and causing a number of respiratory diseases. It is absorbed by the soil particles such that it persists for longer duration and kills the essential microbial fauna. It does not dissolve in water but it dissolves in the adipose tissues of the aquatic animals. So, in water, it entered into the aquatic food chain and its successive consumption resulted in biomagnification.Hence, the correct answer is 'Air, water and soil'.
