Answer: (C) Stratosphere

The ozone layer is located in the Stratosphere, 15–35 km above Earth's surface. It absorbs the majority of the Sun's harmful ultraviolet (UV-B and UV-C) radiation, protecting life on Earth. The Troposphere is where weather occurs; the Thermosphere and Mesosphere lie above the Stratosphere.
