Which of the following is not correctly matched for the organism and its cell wall degrading enzyme?

The green algae produce cell walls containing polymers similar to land plants. The red algae possess complex composite cell walls made up of cellulose, xylan or mannan fibrils and extensive matrix polysaccharides and so in short, algal cell wall is made up of cellulose and thus can be degraded by the enzyme cellulase. Whereas, methylase is the enzyme that adds a methyl group to the adenine of the RNA. Thus, the correct answer is option A.
