Correct Answer:
C. UV Rays
The ozone layer, located in the Earth's stratosphere, plays a vital role in protecting life on our planet by absorbing harmful radiation from the sun. Specifically, it restricts most of the sun's UV Rays (Ultraviolet Rays) from reaching the Earth's surface. Exposure to excessive UV radiation, particularly UV-B and UV-C, can cause skin cancer, cataracts, and harm to ecosystems.
- X-rays and Gamma Rays are also high-energy electromagnetic radiation, but they are mostly absorbed much higher in the atmosphere, above the ozone layer.
- Infrared rays are a form of electromagnetic radiation associated with heat. While they reach the Earth's surface and contribute to the greenhouse effect, the ozone layer does not primarily restrict them in the same protective manner as it does UV rays.
