Match the List I with List II and select the correct answer using the codes given below the lists:

  List - I                                           List - II
A) Teflon                        i) Ozone layer depletion

B) Pyrene                       ii) Non-biodegradable insecticide

C) DDT                            iii) Non-stick cookwares and insulator

D) Freon                         iv) Fire extinguisher

A. Teflon is a trademark name for polytetrafluoroethylene, a chemical coating. It is utilized to make an insulator as well as a nonstick surface.

B. Pyrene is a polycyclic aromatic hydrocarbon widely used in fire extinguishers.

C. Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound. It is a non - biodegradable insecticide.

D. Freon is made up of a number of simple “fluorinated aliphatic organic compounds” used as refrigerants and as aerosol propellants. These include the chlorofluorocarbons that cause ozone depletion.

Hence, the correct answer is option (C)  iii iv ii i
