(D) An electrostatic precipitator $(ESP)$ is a highly efficient device used in thermal power plants to control air pollution.It works on the principle of corona discharge,where electrodes generate a corona that releases electrons.These electrons attach to dust particles,giving them a negative charge.The charged dust particles are then attracted to collecting plates that are grounded or positively charged.This process is capable of removing over $99 \%$ of the particulate matter present in the exhaust gases of thermal power plants.

An electrostatic precipitator is used in thermal power plants to remove $...........$ from the exhaust gases.
