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?

1. Statement 1 is incorrect. The Buland Darwaza at Fatehpur Sikri, built by Akbar, is predominantly constructed using red sandstone, although it incorporates some use of white marble for inlay decoration. The claim that white marble was the primary material used in making it is false. Similarly, the main structures at Fatehpur Sikri, including the associated Dargah of Salim Chishti (which might be considered a Khankah or part of one), extensively use red sandstone, though the tomb itself is encased in white marble (added later). 2. Statement 2 is incorrect. The Bara Imambara and Rumi Darwaza at Lucknow, built by Nawab Asaf-ud-Daula in the late 18th century, are primarily constructed using brick and lime mortar, finished with stucco ornamentation (Lakhauri bricks). They are characteristic of Awadhi architecture and do not primarily use red sandstone and marble in their main structure like Mughal buildings in Delhi or Agra.
