Correct answer is (c) Catalase
For explanation I would say: Catalase is derived from the fungal fermentation and is an enzyme that converts hydrogen peroxide to water and molecular oxygen. Cellulase is an enzyme that converts cellulose to glucose and galactose. Pullulanase cleaves only a-1, 6-links to give straight-chain maltodextrins. Pectinesterase is an enzyme which releases methanol from the pectyl methyl esters.
