Options

A. Vocal cords
B. Forceful expulsion of air from lungs
C. Forceful expulsion of air from nares
D. Forceful inhalation

Answer

To answer the question "Snake produces hissing sound through," we can break down the explanation step by step:

### Step-by-Step Solution:

1. **Understanding Snake Anatomy**:
- Snakes have a structure in their throat called the glottis, which is involved in their breathing process.

2. **Breathing Mechanism**:
- Snakes primarily breathe through their nostrils (nares). The glottis opens and closes as they breathe.

3. **Normal Breathing**:
- Under normal circumstances, the breathing process in snakes is quiet and does not produce any sound.

4. **Response to Threat**:
- When a snake feels threatened or encounters a potential enemy, its breathing rate increases significantly.

5. **Forceful Expulsion of Air**:
- This increased breathing leads to a forceful expulsion of air from the lungs through the nares.

6. **Production of Hissing Sound**:
- The rapid and forceful expulsion of air creates the characteristic hissing sound that snakes are known for.

7. **Conclusion**:
- Therefore, the correct answer to the question is that snakes produce a hissing sound through the forceful expulsion of air from their nares.

### Final Answer:
**Snakes produce hissing sound through the forceful expulsion of air from their nares.**
