Solution
The correct option is D SPM
The electrostatic precipitators work on the principles of the electrostatic force. It consists of discharge wires and collecting plates. An application of high voltage to the discharge wires create an electric field between the wires and the plates. When the air containing the dust and suspended particulate matter like aerosols and solid particles is passed through this electrostatic field, the particles get charged and are collected onto the plate as per Coulomb's Law. This makes the air free of dust and SPM. Electrostatic precipitators are used in vehicles and coal-fired power plant to restrict the entry of dust and SPM into the atmosphereSo, the correct answer is 'SPM'
