Answer

To determine which sexually transmitted diseases (STDs) are not completely curable, we will analyze the options based on their causative agents and available treatments.

### Step-by-Step Solution:

1. **Understanding STDs**:
- STDs are infections that are primarily spread through sexual contact. They can also be transmitted through infected blood transfusions and poor hygiene.

2. **Identifying the Causative Agents**:
- Each STD is caused by a specific pathogen, which could be a bacterium or a virus. The type of pathogen influences the treatment options and the curability of the disease.

3. **Analyzing the Options**:
- **Option A**: Includes Chlamydia, Gonorrhea, and Trichomoniasis.
- All these are caused by bacteria and are treatable with antibiotics, making them curable.

- **Option B**: Includes Canker sore, Syphilis, and Genital Warts.
- Canker sore (caused by Haemophilus ducreyi) and Syphilis (caused by Treponema pallidum) are bacterial and treatable with antibiotics. Genital warts are caused by the human papillomavirus (HPV), which is not completely curable but manageable.

- **Option C**: Includes AIDS, Syphilis, and Hepatitis B.
- AIDS is caused by the HIV virus, which currently has no cure, only treatment to manage symptoms. Syphilis is bacterial and curable, while Hepatitis B is viral and manageable but not completely curable.

- **Option D**: Includes AIDS, Genital Herpes, and Hepatitis B.
- All these diseases are caused by viruses. There is no complete cure for AIDS, Genital Herpes, or Hepatitis B; only symptom management is possible.

4. **Conclusion**:
- Based on the analysis, the diseases that are not completely curable are found in **Option D**: AIDS, Genital Herpes, and Hepatitis B.

### Final Answer:
**D. AIDS, Genital Herpes, and Hepatitis B are not completely curable STDs.**
