If a question is about protection from harmful ultraviolet rays the answer will be linked with what?
Answer and explanation
Correct answer: Ozone layer of stratosphere
The ozone layer in the stratosphere absorbs much of the Sun’s harmful ultraviolet radiation, especially UV-B and UV-C, so option B is correct. Helium in the exosphere does not provide this shield; meteors are associated with the mesosphere, and dust in the troposphere is not a reliable UV-protection layer. The key association is ozone–stratosphere–UV protection.
