Options

A. To reduce the emission of sulphur dioxide in exhaust fumes
B. To increase efficency of automobiles engines
C. To use sulphur removed from petroleum for commercial purposes
D. To increase the life span of engine silencers

Explanation

### Step-by-Step Solution:

1. **Understanding the Composition of Petroleum Products**:
- Petroleum products, such as petrol and diesel, often contain sulfur compounds.

2. **Identifying the Harmful Effects of Sulfur**:
- Sulfur is known to be a toxic and harmful gas. When burned, it can produce sulfur dioxide (SO₂), which is a significant pollutant.

3. **Impact on the Environment**:
- The emissions of sulfur dioxide contribute to the formation of acid rain. Acid rain can severely damage vegetation, buildings, and aquatic ecosystems.

4. **Effects on Human Health**:
- Sulfur dioxide is also linked to respiratory problems in humans. It can cause conditions such as bronchitis, leading to difficulty in breathing and other health issues.

5. **Damage to Vegetation**:
- In plants, sulfur can lead to chlorosis, which is a condition characterized by yellowing of leaves due to insufficient chlorophyll. This affects the plant's ability to photosynthesize effectively.

6. **Conclusion**:
- Therefore, it is necessary to remove sulfur from petroleum products to reduce the emission of sulfur dioxide, minimize environmental damage, and protect human and animal health.
