Which of the following architectural monuments features the first true Islamic dome and true arch built in India according to Islamic architectural principles?

💡 Solution & Explanation

The Alai Darwaza, constructed by Alauddin Khalji as the southern gateway of the Quwwat-ul-Islam Mosque, represents the earliest surviving structure in India built using true Islamic architectural principles of arches and domes. Earlier monuments often relied on the corbelled bracket system rather than true voussoir arches. Indo-Islamic architecture is a prominent topic in medieval Indian art and culture.
