Question

Quizplus · Accepted Answer

The ozone layer plays a crucial role in shielding Earth's surface from harmful ultraviolet radiation, which can damage or kill living organisms. During the Precambrian era, the development of the ozone layer was particularly important as it allowed for the emergence of more complex life forms that could survive on the surface of the Earth. Therefore, B is the best choice. A, C, and D are inaccurate as they do not relate to the role of the ozone layer in protecting Earth's surface from harmful radiation.
