The correct choice is (b) Polymerized gel entrapment

Easy explanation: Entrapment is a method which involved entrapment of enzyme within suitable gel or fiber. Entrapment can be achieved in 2 ways: Polymerized gel entrapment and microencapsulation. Polymerized gel entrapment is done by using polyacrylamide which is prepared by using aqueous solutions of acrylamide and N, N-methylene-bisacrylamide [BIS] in presence initiators and accelerators.
