B. Trichonympha
C. Trypanosoma
D. Giardia

Answer

### Step-by-Step Solution:

1. **Understanding Vaginitis/Leucorrhea**:
- Vaginitis, also known as Leucorrhea, refers to the inflammation of the vagina, which can lead to abnormal discharge, itching, and discomfort.

2. **Identifying the Cause**:
- To determine what causes vaginitis, we need to evaluate the given options.

3. **Evaluating Option 1 - Trichomonas**:
- Trichomonas is a protozoan parasite known to cause vaginitis. This is the correct answer as it directly relates to the inflammation of the vagina.

4. **Evaluating Option 2 - Trichonympha**:
- Trichonympha is not associated with vaginitis. Instead, it is a symbiotic organism that helps termites digest cellulose. Therefore, this option is incorrect.

5. **Evaluating Option 3 - Trypanosoma**:
- Trypanosoma is a genus of parasites that cause diseases such as African trypanosomiasis (sleeping sickness) and is transmitted by the tsetse fly. This option does not relate to vaginitis, making it incorrect.

6. **Evaluating Option 4 - Giardia**:
- Giardia is a protozoan that causes giardiasis, which affects the gastrointestinal tract. It is not related to vaginitis, so this option is also incorrect.

7. **Conclusion**:
- Based on the evaluations, the correct answer to the question is **Option 1 - Trichomonas**, as it is the only organism listed that causes vaginitis.
