Detailed Solution

Concept- The stratosphere contains ozone. The stratosphere is a layer of the atmosphere that contains ozone. It shields the planet from UV rays.
Refrigerators leak gasses like CFCs that harm the ozone layer. The earth's surface is exposed to UV radiation because of ozone holes. In humans, it results in mutation and skin cancer.
The ozone layer acts as an invisible shield and provides protection from the harmful ultraviolet (UV) radiation coming from the sun. Particularly the ozone layer gives protection against the UV radiation, known as UV-B, which causes sunburn. Inhaling ozone can result in damaging the lungs. Also, low amounts of ozone can cause chest pain, coughing, shortness of breath and throat irritation.
Hence, the correct answer is option 1.
