Correct Answer:
B. It protects us from harmful radiation.
Explanation:
The ozone layer acts as a shield by absorbing the majority of the sun's harmful ultraviolet (UV) radiation. Its depletion is a major concern because it allows more UV rays to reach the Earth's surface, which can cause skin cancer, cataracts, and immune system suppression in humans, while also damaging ecosystems and marine life.
