Q. Which building constructed under the Delhi sultanate is one of the first buildings in India to be built using an Islamic architectural style?
Answer:
Alai Darwaza
Notes: The Alai Darwaza, built in 1311 AD by Sultan Alauddin Khilji, is the main southern gate of the Quwwat-ul-Islam Mosque in the Qutub Minar Complex.
