Solution
The correct option is B Hawks
Highest accumulation of insecticide could be found in hawk because it is at the top of the food web. It will obviously reach all other organisms in the food web, but the maximum is found in hawk. This is scientifically termed as 'biological magnification'.
Biological magnification often refers to the process of transfer of harmful chemicals in increasing concentration in successive trophic levels.
