What do UVC rays primarily do?

Reach the earth's surface
Get absorbed by the ozone layer
Cause skin cancer
Contribute to global warming

The correct answer is: Get absorbed by the ozone layer

The other options, such as A, C, and D, are incorrect because while UVC rays can reach the earth's surface, they are mainly blocked by the ozone layer. Additionally, while UVC rays can also cause skin cancer, it is not their primary function. And while UVC rays do contribute to global warming, it is not their main purpose. Thus, B is the best answer as it correctly states that UVC rays are primarily absorbed by the ozone layer.
