C. Hydrogen sulphides
D. Sulphure

Answer

To solve the question regarding the pollutant that causes a burning sensation in the throat and eyes, as well as vomiting, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Symptoms**: The question mentions specific symptoms: burning sensation in the throat and eyes, and vomiting. We need to find a pollutant that is known to cause these symptoms.

2. **Consider the Options**: The options provided are:
- A) Hydrogen cyanides
- B) Arsenic
- C) Hydrogen sulfides
- D) Sulfur dioxide

3. **Analyze Each Option**:
- **Hydrogen cyanides**: This is a toxic compound but is primarily known for causing respiratory issues and can lead to asphyxiation rather than the specific symptoms mentioned.
- **Arsenic**: This is a well-known poison that can cause various health issues, but it does not typically cause immediate burning sensations in the throat and eyes.
- **Hydrogen sulfides**: This gas is known to have a strong odor (like rotten eggs) and can cause irritation in the eyes and respiratory tract, leading to burning sensations and nausea.
- **Sulfur dioxide**: This gas can cause respiratory problems and irritation but is less likely to cause vomiting compared to hydrogen sulfides.

4. **Select the Most Likely Option**: Based on the analysis, hydrogen sulfides (Option C) is the most likely pollutant to cause the symptoms described in the question.

5. **Conclusion**: Therefore, the correct answer to the question is **C) Hydrogen sulfides**.
