Solution
The correct option is D Fimbriae
Fimbriae are the hair-like projection, shorter than pili and covered the surface of the bacterial cells. It helps the bacteria to attach the surface of the target tissues or cells. Whereas pili are the projection for the exchange of genetic material between two bacterial cells, flagella is for locomotion and anchoring junction is the connection between two cells for the movement of water of nutrients. Thus, the correct answer is option D.
