Solution

The correct option is D

DDT


Noble prize in physiology or medicine in the year 1948 was awarded to Paul Muller for his discovery of the high efficiency of dichloro diphenyl trichloroethane (DDT) as a contact poison against several arthropods. Although DDT was first synthesized in 1874 by a Viennese pharmacist, Othmar Zeidler, he did not investigate the properties of the new substance but simply published his synthesis. Field trials of the compound synthesized by Muller showed it to be effective against a wide variety of pests including the common housefly, the louse, Colorado beetle, and mosquito.
