The correct option is B Statement 1 is true, statement 2 is false
The ozone layer is present in the stratosphere. It shields the surface of the Earth from ultraviolet (UV) radiation from the Sun. This radiation is highly damaging to organisms, for example, it is known to cause skin cancer in human beings. Ozone depletion is caused by chlorofluorocarbons.
Global warming is due to retention of infrared light which retains heat on earth.
