Best answer
Right option is (b) lactase

Best explanation: Immobilized lactase is used in the treatment of whey as the fats and proteins in the milk emulsion tend to coat the biocatalyst which reduces their apparent activity and increases the chances microbial colonization. Immobilized raffinase is used to remove raffinose. Whereas immobilized invertase helps in production of glucose syrups. Rennet is used in cheese making industry.
