Options

• hydrogen

Answer 1

Taj Mahal is threatened due to the effect of sulphur dioxide.

Explanation:

Sulphur dioxide (SO₂) causes erosion of building materials such as limestone and marble, which are components of the Taj Mahal. The pollution, particularly from nearby industrial sources like the Mathura refinery, leads to acid rain formation that corrodes and deteriorates the marble surface of the monument, endangering its preservation.
