The correct answer is B. Refrigerator.
Chlorofluorocarbons (CFCs) are a group of man-made chemicals that were once widely used in refrigerators, air conditioners, and aerosol cans. However, CFCs are very harmful to the environment, as they deplete the ozone layer. The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. Depletion of the ozone layer can lead to an increase in skin cancer and other health problems, as well as damage to plants and ecosystems.
In 1987, the Montreal Protocol was signed by 197 countries. The Montreal Protocol is an international treaty that aims to protect the ozone layer by phasing out the production and use of CFCs and other ozone-depleting substances. India ratified the Montreal Protocol in 1992.
In recent years, India has taken several steps to reduce its reliance on CFCs. In 2016, the Indian government announced a ban on the production and import of CFCs. The government has also provided financial assistance to businesses that have switched to alternative refrigerants.
The production of CFCs is now proposed to be banned in India. This is a positive step, as it will help to protect the ozone layer and reduce the risk of health problems and environmental damage.
The other options are incorrect. Televisions do not use CFCs. Tube lights use a different type of gas, called mercury vapor. Cooking gas does not use CFCs.
