What helps block ultraviolet rays in the atmosphere?
Answer and explanation
Correct answer: Ozone
The ozone layer in the stratosphere absorbs a large proportion of the Sun’s harmful ultraviolet radiation, so option D, ozone, is correct. Nitrogen is the most abundant atmospheric gas, but it does not provide the main protective absorption of UV rays. Dust particles can scatter light and oxygen participates in ozone formation, yet neither is the principal atmospheric shield identified in this question.
