Answer: (B)

Verified step by step guidance

1. Identify the key characteristics of bacteria by recalling their cellular structure and reproduction methods.
2. Understand that bacteria are prokaryotic organisms, meaning they do not have a membrane-bound nucleus or other membrane-bound organelles.
3. Recognize that bacteria are unicellular, which means they consist of a single cell rather than multiple cells.
4. Recall that bacteria reproduce primarily through asexual methods such as binary fission, not sexual reproduction.
5. Compare each statement to these characteristics to determine which one accurately describes bacteria.
