विकल्प

• Nitrogen

• Nitrogen

• Chlorofluorocarbon

Answer 1

Chlorofluorocarbon

Explanation:

Chlorofluorocarbons, commonly known as CFCs, were widely used in refrigerators and air conditioners. However, their use has been banned because they damage the ozone layer, leading to its depletion. CFCs break down ozone molecules when released into the atmosphere, thereby creating the harmful ozone hole. Due to this environmental impact, the production and use of CFCs in refrigerators and air conditioners are now banned in many countries, including India.
