Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In the cell wall of blue-green algae and bacteria, there are two important sugar derivatives which are not found anywhere else, i.e., NAG and NAM ($N$-acetyl glucosamine and $N$-acetyl muramic acid), besides a-alanine, $D$-alanine, glutamic acid and diaminopimelic acid.

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
