The correct answer is: A. Taj Mahal
The Taj Mahal is a white marble mausoleum on the south bank of the Yamuna river in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor Shah Jahan (reigned 1628â1658) to house the tomb of his favourite wife Mumtaz Mahal; it also houses the tomb of Shah Jahan himself. The tomb is the centrepiece of a 17-hectare (42-acre) complex, which includes a mosque and a guest house, and is set in formal gardens bounded on three sides by a crenellated wall.
The Taj Mahal is widely recognized as “the jewel of Muslim art in India and one of the universally admired masterpieces of the world’s heritage”. The tomb is the most popular tourist destination in India, attracting about 7â8 million visitors a year.
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure.
The Taj Mahal is one of the most vulnerable monuments to acid rain in the world. The marble of the Taj Mahal is particularly susceptible to the effects of acid rain, which can cause it to discolour and erode.
In recent years, there have been a number of initiatives to protect the Taj Mahal from acid rain. These include the installation of scrubbers at power plants in the area, the planting of trees to help absorb pollutants, and the development of a buffer zone around the monument.
Despite these efforts, the Taj Mahal continues to be affected by acid rain. It is estimated that the marble of the Taj Mahal is losing about 100 milligrams per square meter per year due to acid rain.
If no further action is taken, the Taj Mahal could be seriously damaged by acid rain within the next few decades.
