CFCs are a type of chemical that were once widely used in refrigerators, air conditioners, and other products.

The Montreal Protocol phased out the production and use of CFCs, and as a result, the ozone layer is slowly recovering.<\/p>\n<p>Option A is incorrect because the Montreal Protocol was signed in 1987, not 2001.<\/p>\n<p>Option B is incorrect because the Montreal Protocol was signed in 1987, not 1980.<\/p>\n<p>Option C is the correct answer because the Montreal Protocol was signed in 1987.<\/p>\n<p>Option D is incorrect because the Montreal Protocol was signed in 1987, not 1994.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;2001&#8243;
