Answer 1

The correct option is B Air pollution

Electrostatic precipitators are extensively employed to control air pollution.

It is a device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates. It 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.
