Best answer
The correct option is (c) Cellulase

Best explanation: Cellulase is used to cellulose to glucose and is part of enzyme preparation obtained from Trichoderma Reesei. Enzyme preparation produced from Aspergillus Niger consist of the following:

• Polygalacturonase hydrolyzes 1,4-a-D-galactosiduronic linkages randomly.

• Pectinesterase releases methanol from the pectyl-methyl esters.

• Pectin lyase which cleaves pectin without the necessity of pectin methyl esterase action.

• Hemicellulase which is a mixture of hydrolytic enzymes.
