The Correct Answer is B
DDT or Dichloro-Diphenyl-Trichloroethane is the first modern pesticide and is arguably the best known organic pesticide. It was developed early in World War II, and initially used with great effect to combat mosquitoes spreading malaria, typhus, and other insect-borne human diseases among both military and civilian populations, and as an agricultural insecticide.
The World Health Organization (WHO) is now recommending the indoor spraying with DDT in areas where malaria transmission is constant and high - not just in epidemic areas.
Indoor residual spraying is useful to quickly reduce the number of infections caused by malaria-carrying mosquitoes. IRS has proven to be just as cost effective as other malaria prevention measures, and DDT presents no health risk when used properly. Indoor spraying means applying DDT to walls and the roofs of houses and domestic animal shelters. It destroys the malaria-carrying mosquitoes that land on the surfaces of walls and roofs. This preventive measure can reduce malaria transmission by up to 90%.
