Statement 1 : Taj Mahal is losing its white lustre and getting discoloured.
Statement 2: Pollutants like carbon dioxide and carbon monoxide cause acid rain which corrodes the marble of the monument.

Options

A. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B. Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C. Statement 1 is true but statement 2 is false.
D. Both statements 1 and 2 are false.

Explanation

To analyze the two statements regarding the Taj Mahal and its discolouration due to pollution, we will evaluate each statement step by step.

### Step 1: Evaluate Statement 1
**Statement 1:** Taj Mahal is losing its white lustre and getting discoloured.

- The Taj Mahal, made of white marble, has been reported to be losing its shine and is becoming discoloured due to environmental factors.
- This discolouration is primarily caused by air pollution, including emissions from factories and vehicles.

**Conclusion for Step 1:** Statement 1 is true.

### Step 2: Evaluate Statement 2
**Statement 2:** Pollutants like carbon dioxide and carbon monoxide cause acid rain which corrodes the marble of the monument.

- Acid rain is primarily caused by pollutants such as nitrogen dioxide (NO2) and sulfur dioxide (SO2), not carbon dioxide (CO2) and carbon monoxide (CO).
- When NO2 and SO2 mix with water in the atmosphere, they form acids that fall as acid rain, which can corrode marble and other materials.
- Therefore, while carbon dioxide and carbon monoxide are pollutants, they do not directly cause acid rain.

**Conclusion for Step 2:** Statement 2 is false.

### Step 3: Determine the Relationship Between the Statements
- Since Statement 1 is true and Statement 2 is false, Statement 2 cannot be considered a correct explanation for Statement 1.
- Therefore, we conclude that while the first statement is accurate regarding the discolouration of the Taj Mahal, the second statement incorrectly attributes the cause of acid rain.

### Final Conclusion
- Statement 1 is true.
- Statement 2 is false.
- Statement 2 is not the correct explanation of Statement 1.
