Answer

### Step-by-Step Solution:

1. **Understanding Euro IV Norms**:
- Euro IV norms are regulations set to limit the amount of harmful emissions from vehicles, particularly focusing on reducing sulfur content in fuels.

2. **Sulfur Content Requirements**:
- According to Euro IV norms, the sulfur content in both petrol and diesel should be limited to **50 parts per million (ppm)**. This is a significant reduction compared to previous standards.

3. **Analyzing the Options**:
- **Option 1**: States sulfur levels of 350 ppm in diesel and 150 ppm in petrol. This is actually the requirement for Euro III norms, not Euro IV. Therefore, this option is incorrect.
- **Option 2**: States sulfur levels of 50 ppm in both petrol and diesel. This aligns with the Euro IV requirements, making this option correct.
- **Option 3**: States sulfur levels of 200 ppm in both petrol and diesel. This does not comply with Euro IV norms and is incorrect.
- **Option 4**: States sulfur levels of 200 ppm in diesel and 100 ppm in petrol. This also does not meet the Euro IV standards and is incorrect.

4. **Conclusion**:
- The only correct statement regarding Euro IV norms is that the sulfur level should be **50 ppm in both petrol and diesel**.

### Final Answer:
The true statement about the Euro IV norms is that the sulfur level should be **50 ppm in petrol and diesel both**.
