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:

Step-by-step solution

Smokestacks of thermal power plants, smelters and other industries release particulate and gaseous air pollutants together with harmless gases, such as nitrogen, oxygen, etc. These pollutants must be separated/filtered out before releasing harmless gases into the atmosphere. There are several ways of removing particulate matter; the most widely used of which is the electrostatic precipitator which can remove over 99 per cent of particulate matter present in the exhaust from a thermal power plant.
