Answer:
The correct answer is option B.
Step-by-step explanation:
Both archaea and bacteria are prokaryotes, that is, they do not possess a nucleus and are devoid of membrane-bound organelles. They are the tiny, single-cell species that cannot be observed by the naked human eye. By observing both the species under the microscope, it is found that both of them resemble each other in size and shape. They prevail in the form of cones, rods, coils, and plates. Both these species exhibit flagella, which helps them in the process of locomotion.
