Answer:
The correct option is A) prokaryote
Step-by-step explanation:
The structure can be recognized as a prokaryote because as we can see the cell is simple and lacks nuclear regions as well.
It cannot be a eukaryotic cell because a eukayotic cell is more complex and would have shown the nuclear region.
The structure cannot be a mitochondria because the structure lacks the compartments that the mitochondria possesses.
