The correct answer is B:Wax D
It is due to the presence of wax D, the waxy substance is called mycolic acid which is a lipid found in the cell walls of these bacteria. It also contributes to the unique characteristics of the bacteria that plays a role in the ability of the bacteria to cause the disease. Mycobacterium tuberculosis has a high level of mycolic acids. It gives the acid fast property to the bacteria. For leprosy, mycolic acid gives the unique tissue invading ability to the bacteria.

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:
