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.
Thus, the correct answer is option C.
