Solution

The correct option is B Glycocalyx
Bacteria have proteins on their surface which are identified by the host immune system and then may be subsequently destroyed.

Some bacteria have a special thick and tough mucilage covering covering outside the cell wall called "capsule". This may be made up of polysaccharides and proteins. It masks proteins on the bacterial surface and prevent them from being recognized by the host immune system. It also provides protection from toxic chemicals and drugs.


Fimbriae are finger-like cytoplasmic appendages in bacteria and a few other organisms, which help the cell in the attaching to surfaces.

Flagella are the locomotory appendages found in several unicellular forms like the bacteria.

Endospore is a thick walled structure that is formed within a bacterial cell during unfavorable conditions.
