2. **Analyze the Options**: We have four options to consider:
- A) Ailery muscles
- B) Sternoturgal muscles
- C) Intercostal muscles
- D) Adductor muscles

3. **Evaluate Option A - Ailery Muscles**:
- Ailery muscles are located near the heart and are involved in the circulation of blood in the cockroach. They do not play a role in respiration.
- **Conclusion**: This option is incorrect.

4. **Evaluate Option B - Sternoturgal Muscles**:
- Sternoturgal muscles are located between the sternum and the tergum. They are responsible for the movement that allows air to enter and exit the respiratory system of the cockroach.
- **Conclusion**: This option is correct as it directly relates to respiration.

5. **Evaluate Option C - Intercostal Muscles**:
- Intercostal muscles are found between the ribs in vertebrates and are not present in cockroaches. They are not involved in the respiration of cockroaches.
- **Conclusion**: This option is incorrect.

6. **Evaluate Option D - Adductor Muscles**:
- Adductor muscles are involved in the movement of the mandibles (mouthparts) of the cockroach and are not related to respiration.
- **Conclusion**: This option is incorrect.

7. **Final Answer**: The muscle that deals with respiration in cockroaches is **Option B - Sternoturgal muscles**.
