Right answer is (a) Spent carbon

To explain: Hazardous waste in the purification processes for organic solvents usually generate wastes like spent carbon, spent catalyst and filters with organic liquids in them. Methane, high water content, less water content, are the wastes generated in other treatment methods and not in the purification processes for organic solvents.
