Explanations:The Delhi Sultanate was a period of Muslim rule in India that lasted from the early 13th to the early 16th century. During this time, several cities were established in the Delhi region, each serving as a capital at different points in history. The cities of Delhi-i-Kuhna, Siri, and Jahanpanah were all built during the Delhi Sultanate period and are located in the present-day area of Delhi.
Delhi-i-Kuhna, also known as Old Delhi, was the first city built by Qutb-ud-din Aibak, the founder of the Delhi Sultanate. It was established in the early 13th century and served as the capital of the Delhi Sultanate for a significant period. The city was strategically located and was an important center for trade and administration.
Siri was built by Alauddin Khilji, the second ruler of the Khilji dynasty, in the early 14th century. It was constructed to protect the city from Mongol invasions and was located in the present-day area of Delhi. Siri was known for its strong fortifications and was an important center of power during the Delhi Sultanate.
Jahanpanah was built by Muhammad bin Tughluq, the ruler of the Tughlaq dynasty, in the 14th century. It was located between the cities of Siri and Tughlaqabad and was constructed to provide a safe haven for the people of Delhi during times of conflict. Jahanpanah was an important city during the Delhi Sultanate and served as a capital for a period of time.
Jaunpur, on the other hand, is not a city built during the Delhi Sultanate period. It is located in the state of Uttar Pradesh and was the capital of the Sharqi Sultanate, a separate kingdom that existed from the 14th to the 16th century. The Sharqi Sultanate was not part of the Delhi Sultanate and had its own distinct history and rulers. Therefore, Jaunpur is not a city built during the Delhi Sultanate period and is the correct answer to the question.
