The correct answer is Option C Insertional inactivation of alpha-galactosidase in recombinant bacteria.

This is because – Lysozyme breaks down bacterial cell walls. Cellulase is a cellulose-degrading enzyme found in plant cell walls. Chitinase is a fungal enzyme that tears down the cell wall. Cellulase degrades cellulose, which is found in the cell walls of algae. As a result, methylase does not degrade the cell walls of algae.
