Given below are two statements:

Statement I: Stratospheric ozone is known as 'good ozone'.

Statement II: Ozone at the surface level is a serious health hazard and known as pollutant.

In the light of the above statements, choose the most appropriate answer from the options given below. 

Key Points 

Statement I: Stratospheric ozone is known as 'good ozone'.

• Statement I is correct because stratospheric ozone is a layer of ozone gas in the stratosphere that absorbs harmful ultraviolet (UV) radiation from the sun.
• This protects life on Earth from the harmful effects of UV radiation, such as skin cancer and cataracts.

Statement II: Ozone at the surface level is a serious health hazard and known as pollutant

• Statement II is also correct because ozone at the surface level is a serious health hazard.
• It is a pollutant that can cause respiratory problems, such as asthma and bronchitis. It can also damage crops and plants.

Therefore, both Statement I and Statement II are correct.

Here are some additional details about ozone:

• Ozone: Ozone is a molecule that is made up of three oxygen atoms. It is a colorless gas that has a pungent odor.
• Stratospheric ozone: Stratospheric ozone is found in the stratosphere, which is the layer of the atmosphere that is between 10 and 50 kilometers above Earth's surface.
• Surface ozone: Surface ozone is found in the troposphere, which is the layer of the atmosphere that is closest to Earth's surface.
