Answer

To determine the correct sequence of passage of ova in the female reproductive system of a cockroach, we can break down the process step by step:

### Step-by-Step Solution:

1. **Ovaries**: The ova are developed in the ovaries of the cockroach. Each cockroach has a pair of ovaries, which contain several ovarian tubules.

2. **Germanium**: Once the ova are developed, they first move into a structure called the germanium. This is where the matured ova are stored temporarily.

3. **Vitalarium**: After the germanium, the ova pass into the vitalarium. This structure is involved in the further passage of the ova.

4. **Oviduct**: The next step is the movement of the ova into the oviduct. The oviduct is a tube that connects the ovaries to the vagina.

5. **Vagina**: From the oviduct, the ova then move into the vagina. The vagina serves as the passageway for the ova to exit the reproductive system.

6. **Female Genital Pore**: After the vagina, the ova enter the female genital pore. This is the external opening of the reproductive system.

7. **Genital Pouch**: Finally, the ova move into the genital pouch, which is the chamber that holds the ova before they are laid.

### Final Sequence:
The correct sequence of passage of ova is:
- A) Germanium
- B) Vitalarium
- D) Oviduct
- C) Vagina
- E) Female genital pore
- F) Genital pouch

### Conclusion:
The correct answer is: **A, B, D, C, E, F**.
