Solution
The correct option is C SPM
Coal-burning results in the generation of large quantities of residues obtained from coal.
These residues contain very fine particles that contribute to the formation of suspended particulate matter (SPM).
An electrostatic precipitator (ESP) is a filtration method 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.
