Correct Answer:
B. It protects living organisms from harmful UV radiation.
Explanation:
The ozone layer, located in the stratosphere, acts as a vital shield for Earth by absorbing the majority of the sun's high-energy ultraviolet (UV) radiation. Without this protection, increased levels of UV rays would reach the surface, leading to severe health issues for humans, such as skin cancer and cataracts, while also damaging ecosystems and marine life. By filtering out these harmful rays, the ozone layer ensures the safety and survival of living organisms.
