Best answer
Correct option is (d) Bioleaching

The explanation is: The products of combustion cling to the water tubes, economizer tubes, air preheater tubes and super heater tubes. This lowers the efficiency of the plant by reducing heat transfer. So, regular removal of soot or dust is necessary this method is known as soot blowing.
