Question

Chlorofluorocarbon releases a chemical harmful to ozone.
A.Fluorine
B.Sulphur dioxide
C.Nitrogen peroxide
D.Chlorine

Answer 1

Hint: Chlorofluorocarbon is a poisonous gas for the environment as it is exerted from refrigerators, coolers, air conditioners etc. CFCs are highly toxic for human health too as well as for the environment. In the environment Chlorofluorocarbons are known for depletion of the ozone layer. Ozone layer is a layer which protects the earth from the sun's harmful rays. Reaching directly to the earth surface.

Complete answer:
Option A: fluorine- fluorine is a chemical which is used in the manufacturing of toothpaste. And it is also used as a bleaching agent and disinfectant in water.
Option A is not the correct answer.
Option B: Sulphur dioxide- Sulphur dioxide is a chemical compound which is harmful and toxic. It detoxifies the environment's health. And it is exerted from factories as smoke.
Option B is not the correct answer.
Option C: Nitrogen peroxide- Nitrogen peroxide is used in disinfectants in different types of cleaners. It is used in laboratories to clean the wounds and used as an antiseptic.
Option C is not the correct answer.
Option D: Chlorine- chlorine is a toxic chemical exerted from Chlorofluorocarbon. It contributes a major portion in depleting the ozone layer and also causing various health problems in human beings and animals.
Option D is the correct answer.

Option D is correct.

Note:
As we know, the ozone layer is the protective layer which surrounds the earth from sun harmful rays. In other words it dilutes the concentration of sun rays so that it cannot directly hamper lives. Due to the increase of human activities and technologies, Chlorofluorocarbon is increasing and it is digging holes in the ozone layer as a result the sun rays are not in dilution anymore. Many diseases like- skin diseases, eye infections and mutations in cells are also occurring due to this ozone depletion.
