Best answer
Right choice is (a) Cross-linking

Best explanation: Cross-linking is a method of immobilization which does not require the support/matrix material. The cross-linking occurs between groups of cells/enzymes via polyfunctional reagents. Entrapment, adsorption, and covalent bonding require the use of support/matrix materials.
