The correct answer is: Champaner-Pavagadh.
Champaner-Pavagadh is a UNESCO World Heritage Site located in the Indian state of Gujarat. It is a complex of historical and archaeological sites that includes the ruins of the city of Champaner, which was founded in the 11th century by the Chaulukya dynasty. The city was later conquered by the Mughals in the 16th century and abandoned.
The Champaner-Pavagadh complex is a UNESCO World Heritage Site because of its “outstanding universal value”. The site is a “remarkable example of a medieval city” and contains “a wealth of architectural and archaeological remains”. The site is also important because it is a “testimony to the cultural and religious interaction between Hindu and Muslim civilizations”.
The other options are incorrect because they are not UNESCO World Heritage Sites. Ahmedabad is a city in Gujarat that is known for its historical architecture. Rani ki Vav is a stepwell located in Patan, Gujarat. Dholavira is an archaeological site located in Kutch district, Gujarat.
