The question is incomplete as it does not have the options which are:
A) most likely a bacterium.
B) most likely a eukaryote.
C) most likely an archaeon.
D) either a bacterium or an archaeon
C) most likely an archaeon.
Answer:
The correct answer will be option-C
Explanation:
Archaea is a domain of micro-organism which is distinct from the prokaryotic bacteria and the eukaryotes.
The domain was separate from the bacteria on the basis that the micro-organism lack the peptidoglycan layer present in the bacteria and the difference in the RNA.
Since in the given question, the organism shows the characteristics of a bacteria-like coccoid, lack a nucleus but the lack of peptidoglycan layer help determine that the microbe belongs to the Araceae.
Thus, Option-C is the correct answer.
