Answer

To solve the question regarding where ova with various stages of development are found, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Question**: The question asks where ova with various stages of development are found in the female reproductive system of a cockroach.

2. **Understand the Female Reproductive System**: The female reproductive system of a cockroach consists of several parts, including the germarium, vagina, vitalarium, and seminal receptacles.

3. **Examine Each Option**:
- **Germarium**: This is the part of the ovary where the development of ova (oocytes) begins. It contains oogonia that develop into oocytes.
- **Vagina**: This is primarily a passage for the ova but does not contain developing ova.
- **Vitalarium**: This part stores the oocytes after they have been formed in the germarium.
- **Seminal Receptacles**: These are involved in the storage of sperm and not related to the development of ova.

4. **Focus on the Germarium**: The germarium is specifically where the various stages of oocyte development occur. It is responsible for the conversion of oogonia into oocytes.

5. **Conclusion**: Since the germarium is where the ova with various stages of development are found, the correct answer to the question is **option A: Germarium**.
