Tropospheric ozone .
a. is caused by poor farming techniques
b. is produced through the interaction of heat and UV light, with nitrogen oxides and carbon-containing compounds
c. is a primary pollutant
d. protects Earth from most of the harmful UV radiation
e. binds with hemoglobin, preventing binding with oxygen in red blood cells

Tropospheric ozone is produced through interaction of heat and UV light, with nitrogen oxides and carbon containing compounds.

Option: D

Explanation:

In earth's atmosphere there are total five layers: Troposphere, Stratosphere, Mesosphere, Ionosphere and Exosphere. Stratosphere is known as Ozonosphere where ozone layer is present with the key constituent ozone. Ozone layer is very important as it protects whole environment from harmful UV rays coming from space.

Tropospheric ozone is produced through the interaction of heat and UV light with nitrogen oxides and carbon containing compounds. Ozone plays a dual role in environment when it is in lower surface area it is a harmful gas and when it is in atmospheric layer it is a life saving layer.
