Geography (CDS) Pollution

With reference to ground-level ozone, consider the following statements

Statement-I: Ground-level ozone is a colorless and highly irritating gas that forms near the Earth's surface, typically within two miles above the ground.
Statement-II: Ground-level ozone is emitted from sources such as vehicles, power plants, factories, and other combustion sources.

Which one of the following is correct in respect of the above statements?

Both Statement-I and Statement-II are correct, and Statement-II is the correct explanation for Statement-I

Both Statement-I and Statement-II are correct, and Statement-II is not the correct explanation for Statement-I

Statement-I is correct, but Statement-II is incorrect

Statement-I is incorrect, but Statement-II is correct

Ground-level ozone is a colorless and highly irritating gas that forms near the Earth's surface, typically within two miles above the ground.

Ground-level ozone is not directly emitted from specific sources. It is formed through complex interactions between Nitrogen Oxides (NOx), Volatile Organic Compounds (VOCs), and carbon monoxide emitted from vehicles, power plants, factories, and other combustion sources. These compounds undergo cyclic reactions in the presence of sunlight to generate ground-level ozone.
Therefore, only Statement-I is correct, and Statement-II is incorrect.

Hence option 3rd is correct.
