Which of the following cell is prokaryote ?

Options

A. Virus
B. Bacterium
C. Both A and B
D. Fungus.

Answer

To determine which of the following cells is a prokaryote, we need to analyze each option provided:

1. **Virus**:
- Viruses are not classified as prokaryotes or eukaryotes. They lack cellular structure and do not have a nucleus or membrane-bound organelles. They can only replicate inside a host cell and do not exhibit characteristics of living organisms outside of that context.

2. **Bacteria**:
- Bacteria are single-celled organisms that are classified as prokaryotes. They lack a nucleus and membrane-bound organelles, which are defining features of prokaryotic cells. Therefore, bacteria fit the definition of prokaryotes.

3. **Both A and B**:
- Since viruses are not prokaryotes, this option is incorrect. Only bacteria are prokaryotic.

4. **Fungus**:
- Fungi are eukaryotic organisms. They possess a nucleus and membrane-bound organelles, which disqualifies them from being prokaryotes.

Based on this analysis, the only prokaryotic cell among the options is **bacteria**.

**Final Answer**: The prokaryotic cell is **bacteria**.
