The correct answer is: A. Tourists.
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 8 million visitors a year.
The Taj Mahal is threatened by a number of factors, including air pollution, water pollution, and acid rain. The marble of the Taj Mahal is particularly susceptible to damage from acid rain, which is caused by the emission of sulfur dioxide and nitrogen oxides into the atmosphere. These pollutants react with water vapor in the atmosphere to form sulfuric acid and nitric acid, which then fall to the ground as acid rain.
The acid rain corrodes the marble of the Taj Mahal, causing it to turn yellow
and black. The Taj Mahal is also threatened by the increasing number of tourists who visit the site each year. The foot traffic and the emissions from vehicles and other sources of pollution contribute to the degradation of the Taj Mahal.The Indian government has taken a number of steps to protect the Taj Mahal, including installing air purifiers and water filters, and banning the use of vehicles within a certain radius of the site. However, these measures have not been enough to prevent the Taj Mahal from continuing to deteriorate.
In conclusion, the Taj Mahal is greatly affected by tourists. The increasing number of tourists who visit the site each year contributes to the degradation of the Taj Mahal. The Indian government has taken a number of steps to protect the Taj Mahal, but these measures have not been enough to prevent the Taj Mahal from continuing to deteriorate.
