• C. Milk is a good carrier of DDT.
• D. DDT does not undergo bioconcentration, when it enters in food chain.

Answer 1

The correct option is D DDT does not undergo bioconcentration, when it enters in food chain.

DDT (dichlorodiphenyltrichloroethane) is a colourless, crystalline, tasteless and almost odourless organochloride known for its insecticidal properties. It is a non-biodegradable, water-insoluble, chlorinated hydrocarbon once used worldwide as a major insecticide, especially in agriculture. In recent years, knowledge of its adverse impact on the environment has led to restrictions in its use. It is lipophilic, so, undergo bioconcentration when it enters into food chain. Milk is a carrier of DDT cause, DDT enters into food chain. Thus, the correct answer is option D.
