Options

A. only I is correct
B. only III is correct
C. I and II are correct
D. II and III are correct

Answer

To analyze the statements regarding the case study of the Taj Mahal, we will evaluate each statement one by one.

### Step-by-Step Solution:

1. **Evaluate Statement I**:
- The first statement claims that the corroding of the marble of the monument is caused by carbon dioxide and sulphur dioxide.
- This statement is **correct** because the corrosion of marble is primarily due to acid rain, which is formed from the reaction of carbon dioxide and sulphur dioxide in the atmosphere. Acid rain can lead to the deterioration of marble structures.

2. **Evaluate Statement II**:
- The second statement states that suspended soot particles emitted by the Mathura oil refinery cause the yellowing of the marble.
- This statement is also **correct**. The phenomenon known as "marble cancer" refers to the yellowing and damage of marble due to suspended particulate matter, including soot from industrial emissions.

3. **Evaluate Statement III**:
- The third statement suggests that one of the steps to save the Taj is to use CNG and LPG in the automobiles in the Taj zone.
- This statement is **correct** as well. Using cleaner fuels like CNG (Compressed Natural Gas) and LPG (Liquefied Petroleum Gas) reduces emissions of harmful gases such as sulphur dioxide and nitrogen oxides, which contribute to acid rain and, consequently, the corrosion of marble.

### Conclusion:
All three statements are correct regarding the pollution affecting the Taj Mahal.

### Final Answer:
I, II, and III are all correct statements.
