What is the full form of DDT?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Dichlorodiphenyltrichloroethane
DDT stands for dichlorodiphenyltrichloroethane, a chlorine compound once widely used as an insecticide against mosquitoes. It breaks down very slowly and builds up in food chains, so its use has been banned or restricted in many countries.
