Correct answer and explanation

Correct answer: Stratosphere

Explanation: āœ… Correct Answer: B) Stratosphere šŸ“š Explanation: The Ozone layer is concentrated in the lower portion of the Stratosphere, typically between 15 to 35 kilometers above the Earth's surface. It absorbs about 97% to 99% of the Sun's medium-frequency ultraviolet light, which otherwise would potentially damage exposed life forms. Depletion of this layer due to CFCs was a major environmental concern in the late 20th century.
