Solution

C.

DDT

DDT is the most hazardous, non-biodegradable insecticide, which is fat soluble but insoluble in water. It Persists in the environment for a very long period. Being fat soluble, it accumulates in the animal tissue and gets concentrated at different trophic levels of the food chain. At each step, DDT is more concentrated. This is also called biomagnification.
