Explanation:

Ozone present in the stratosphere, acts as a protection from U.V. light. Without this protective shield, all life would be more susceptible to cancer, impaired immunity and other health issues. Whereas the ozone present in the troposphere, which is close to earth surface, can damage our lungs. Hence it is not good for breathing. Hence option 2nd is correct.
