The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Tegmina**: Tegmina are a specific type of wing found in certain insects, including cockroaches. They are the forewings, which are the first pair of wings. 2. **Location of Tegmina**: In cockroaches, the tegmina arise from the mesothorax, which is the middle segment of the thorax. 3. **Pair of Wings in Cockroaches**: Cockroaches have two pairs of wings. The first pair is the tegmina, and the second pair arises from the metathorax, which is the hind segment of the thorax. 4. **Function of Tegmina**: The primary function of the tegmina is to cover the hind wings when the cockroach is at rest. They act as protective covers rather than functioning in flight. 5. **Hind Wings**: The hind wings, which are located beneath the tegmina, are transparent and membranous. These wings are the ones that are actually used for flight. 6. **Conclusion**: Based on the information, tegmina are not used in flight; instead, they serve as wing covers for the hind wings. Therefore, the correct answer is that tegmina function as wing covers and are not used in flight, which corresponds to both options B and C. **Final Answer**: Tegmina are functions as wing covers (B) and are not used in flight (C), so the correct choice is both B and C. ---
