Answer:
The correct answer is B. Bacteria.
Prokaryotes are a group of organisms that lack a nucleus and other membrane-bound organelles. They are characterized by their simplicity in structure and are considered the most ancient and primitive forms of life on Earth. Bacteria are the primary examples of prokaryotes. They are single-celled organisms that lack a nucleus and have a relatively simple cellular structure.
On the other hand, plants, fungi, and animals are eukaryotes. Eukaryotes are organisms that have cells with a true nucleus and other membrane-bound organelles. Plants, fungi, and animals are multicellular organisms that are more complex in structure compared to prokaryotes.
