Answer

To solve the question regarding the effects of sulfur dioxide (SO2), we will analyze each statement provided:

1. **Statement I: Sulphur dioxide causes respiratory diseases in human beings.**
- Sulfur dioxide is known to irritate the respiratory system. It can lead to coughing, mucus secretion, and can exacerbate conditions such as asthma and chronic bronchitis. Therefore, this statement is **correct**.

2. **Statement II: Sulphur dioxide causes red haze in the traffic.**
- The red haze in traffic is primarily caused by nitrogen dioxide (NO2), not sulfur dioxide. Nitrogen dioxide is a reddish-brown gas that contributes to the brown haze often seen in urban areas. Therefore, this statement is **incorrect**.

3. **Statement III: Sulphur dioxide causes irritation of the eyes.**
- Sulfur dioxide is a known irritant to the eyes, causing discomfort and irritation upon exposure. Therefore, this statement is **correct**.

Now, let's summarize the findings:
- Statement I is correct.
- Statement II is incorrect.
- Statement III is correct.

Thus, the correct option includes statements I and III.

### Final Answer:
The correct option is that Sulphur dioxide causes:
- I. Respiratory diseases in human beings.
