Answer:
The correct answer will be option-D
Explanation:
A biofilm is the matrix enclosed multicellular communities formed of wither single species or multiple species. The biofilms formed are covered by the self-produced extracellular material composed of carbohydrate.
The formation of the biofilm is a dynamic and universal process which are formed during the unfavourable conditions so a biofilm can withstand a harsh condition like antimicrobial agents like chloramphenicol.
The formation of biofilm allows the attachment of the micro-organism to different substrates and also microbes easily communicate with each other.
Thus, option-D is the correct answer.
