Given below are two statements.

Statement I : Electrostatic precipitator is most widely used in thermal power plant.

Statement II : Electrostatic precipitator in thermal power plant removes ionising radiations.

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

Statement I is correct but statement II is incorrect.
SI: Electrostatic precipitators are indeed widely used in thermal power plants. They are effective in removing
particulate matter from gases produced during the combustion of fossil fuels. 
SII: Electrostatic precipitators are not designed to remove ionising radiations. Their main purpose is to capture and collect particulate matter, such as dust and ash, by utilising an electrostatic charge.
