Solution
The correct option is C DDT
Rotenone and pyrethrum are the plant derived insecticides, which are very toxic to insects but least toxic to other organisms and are readily oxidised to prevent any accumulation in crop or soil. Humulin is a genetically engineered insulin which works by lowering the blood sugar level.DDT (dichloro, diphenyl, trichloroethane) is long chain stable and fat soluble hydrocarbon, which is readily accumulated in fat tissues of organisms. Slow metabolism and excretion of DDT causes its accumulation in fat tissues of organisms (biomagnifications), particularly affecting the top consumers (carnivores) causing decrease in their population size. This makes option C correct.
