Solution
The correct option is C DDT DDT (dichlorodiphenyltrichloroethane) is a colorless, crystalline, tasteless and almost odorless organochloride known for its insecticidal properties. DDT has been formulated in almost every conceivable form, including solutions in xylene or petroleum distillates, emulsifiable concentrates, water-wettable powders, granules, aerosols, smoke candles and charges for vaporizers and lotions. First synthesized in 1874, DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Mller in 1939.
