SSC CGL 2025 PYQ — Question 50

The correct answer is option 2 i.e. Red sandstone.

The double-storeyed gates of Purana Qila (Old Fort) in Delhi, such as the Bara Darwaza, are quintessential examples of Indo-Islamic architecture from the 16th century. These massive structures were primarily constructed using red sandstone, often finished with white marble inlays for decorative contrast. The use of red sandstone provided both structural durability and a majestic aesthetic, characteristic of the era of Sher Shah Suri and later Mughal influence.
