• C. Ozone layer
• D. Oxygen layer

Answer 1

The correct option is C

Ozone layer

Explanation for correct option:

Option C

Ozone layer:

• Ozone layer is a protective layer present in the stratosphere region.
• The ozone layer absorbs the harmful ultraviolet rays of the sun and prevents them from reaching the earth's surface.
• Due to a decrease in the concentration of ozone in the air, the harmful ultraviolet rays enter the earth's lower atmosphere to cause skin cancer, cataracts in the eyes, sunburn, etc.

Therefore, option C is correct.
