C. (c) emit sound
D. (d) frighten enemies.

Answer

To answer the question about the main function of halteres (reduced wings) on the metathorax of mosquitoes, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Definition of Halteres**: Halteres are small, club-shaped structures that are modified from the hind wings of certain insects, including mosquitoes. They are located on the metathorax.

2. **Function as Gyroscopes**: The primary function of halteres is to act like vibrating gyroscopes. This means they help in determining the rate of rotation of the insect during flight.

3. **Steering Mechanism**: By providing information about the insect's orientation and movement, halteres function similarly to a steering wheel. This allows mosquitoes to maneuver effectively while flying.

4. **Sensory Organ**: At the base of the halteres, there are sensory organs that help interpret the insect's position in space. This feedback is crucial for maintaining stability during flight.

5. **Stabilization of the Head**: Halteres also play a role in stabilizing the head of the mosquito, ensuring that it remains oriented correctly while the body moves.

6. **Conclusion**: Given these functions, the main role of halteres is to provide balance in flight, which is essential for the mosquito's ability to navigate and control its movements in the air.

### Final Answer:
The main function of halteres on the metathorax of mosquitoes is to **provide balance in flight**.
