To determine the correct answer, let's break down the options:
A) Unicellular eukaryotes: Eukaryotes are organisms that have cells with a nucleus enclosed in a membrane. Examples of eukaryotes include plants, animals, fungi, and certain single-celled organisms such as protists. However, bacteria are not eukaryotes. So option A is incorrect.
B) Unicellular prokaryotes: Prokaryotes are organisms that lack a nucleus and membrane-bound organelles. Bacteria are a type of prokaryote and are known to be unicellular, meaning they are made up of a single cell. Therefore, option B is the correct answer.
C) Multicellular eukaryotes: Multicellular organisms are made up of multiple cells and consist of specialized tissues. While there are multicellular organisms in the microbial world, such as certain types of fungi or algae, bacteria are not multicellular. So option C is incorrect.
D) Multicellular prokaryotes: As mentioned earlier, bacteria are unicellular and do not form multicellular structures. Therefore, option D is incorrect.
In summary, the correct answer is B) Unicellular prokaryotes, as most bacteria are single-celled organisms belonging to the prokaryotic domain.
