Solution

The correct option is B Electrostatic precipitator
Particulate matter can be removed by electrostatic precipitator. It is the most efficient device. An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit. Others are scrubbers.
