Correct option (a) lipo soluble

Explanation

Many of the pesticides, such as DDT, aldrin, and dieldrin are accumulated in the environment. They are fat soluble and generally non-biodegradable. They get incorporated into the food chain and ultimately deposited in the fatty tissues of animals and humans.

In the food chain, because of their build up, they get magnified in the higher trophic levels called biological magnification. The phenomenon of biological magnification is also reported for certain other pollutants such as heavy metals, e.g. mercury, copper, and radioactive substances as strontium-90.
