The presence of ozone in troposphere:

Options

Aprotects us from the UV radiation
Bprotects us from greenhouse effect
Cprotects us from the X -ray radiation
Dgenerates photochemical smog

Correct answer

D. generates photochemical smog

Step-by-step solution

The presence of ozone in troposphere generates photochemical smog. Ozone acts as an important infrared absorber (greenhouse gas), particularly in the upper troposphere, and also is an absorber of solar ultraviolet (UV) radiation.
