Detailed Solution

Concept- Marble makes up the majority of the Taj Mahal. So let's examine what the primary cause of marble degradation is. CaCO3 is the chemical composition of marble. Currently, the factories close to the Taj Mahal region primarily create sulphur and nitrogen oxides. Additionally, the Taj Mahal's marble deteriorates because of the wind's direction.
The Yamuna River, which runs alongside Taj Mahal, is another major reason why these factories were built nearby. These factories now predominantly emit nitrogen oxides and sulphur dioxide, especially the Mathura refinery. The Taj Mahal region experiences acid rain as a result of these oxides and air flow. The Taj Mahal's marble, which is essentially calcium carbonate, deteriorates as a result of this harmful acid rain.
Acid rain is a result of the conversion of sulfuric acid and nitrogen oxides, respectively, into nitric acid and sulfuric acid.
Hence, the correct answer is option (1).
