The genome of how many of the following organisms has been sequenced during HGP.
Human , Yeast , Drosophila , Honey bee , Rice , Wheat , Arabidopsis , Caenorhabditis.

Options

A. Five
B. Six
C. Seven
D. Eight

Answer

To determine how many of the listed organisms have had their genomes sequenced during the Human Genome Project (HGP), we will analyze each organism one by one based on the information provided.

### Step-by-Step Solution:

1. **Human**: The Human Genome Project was primarily focused on sequencing the human genome. This was completed in 2003.
- **Conclusion**: Human genome has been sequenced.

2. **Yeast**: Yeast was the first organism to have its genome sequenced as part of the HGP, completed in 1996.
- **Conclusion**: Yeast genome has been sequenced.

3. **Drosophila (Fruit Fly)**: The genome of Drosophila was sequenced during the HGP and was completed in the year 2000.
- **Conclusion**: Drosophila genome has been sequenced.

4. **Honey Bee**: The honey bee genome project is still ongoing and has not been completed.
- **Conclusion**: Honey bee genome has not been sequenced.

5. **Rice**: Rice was the first food crop to have its genome sequenced as part of the HGP.
- **Conclusion**: Rice genome has been sequenced.

6. **Wheat**: Wheat was not sequenced during the HGP.
- **Conclusion**: Wheat genome has not been sequenced.

7. **Arabidopsis**: The genome of Arabidopsis was sequenced in 1996 as part of the HGP.
- **Conclusion**: Arabidopsis genome has been sequenced.

8. **Caenorhabditis (C. elegans)**: The genome of Caenorhabditis was sequenced during the HGP, completed in 1998.
- **Conclusion**: Caenorhabditis genome has been sequenced.

### Summary of Sequenced Organisms:
- **Sequenced**: Human, Yeast, Drosophila, Rice, Arabidopsis, Caenorhabditis
- **Not Sequenced**: Honey Bee, Wheat

### Final Count:
Out of the listed organisms, **6** have had their genomes sequenced during the Human Genome Project.

### Answer:
**6**
