Which of the following cell wall component can effectively defend against lysozyme?

Concept: Pseudomurein otherwise known as pseudopeptidoglycan is one of the cell wall components of Archaea bacteria. 

They resemble the peptidoglycan layer in function and structure but differ in chemical composition. 

Lysozyme is a defense mechanism in higher animals and they cannot defend against bacteria containing Pseudomurein cell wall.

Hence, the correct option is 2.
