With reference to the cultural history of India, consider the following statements :
1. White marble was used in making Buland Darwaza and Khankah at Fatehpur Sikri.
2. Red sandstone and marble were used in making Bara Imambara and Rumi Darwaza at Lucknow.
Which of the statements given above is/are correct ?

Correct Option: (d) Neither 1 nor 2

Statement 1 is incorrect because Buland Darwaza and structures at Fatehpur Sikri were constructed primarily using red sandstone, with white marble used sparingly for inlay work and domes. Statement 2 is incorrect because the Bara Imambara and Rumi Darwaza in Lucknow were built predominantly using brick and lime plaster, rather than red sandstone and marble. Thus, neither statement is correct.
