Who had founded the city of Jaunpur?

Firoz Shah Tuglaq

The correct answer is Option 2- Firoz Shah Tuglaq

Jaunpur's foundation is attributed to Sultan Firoz Shah Tughlaq (1351-1388), a ruler of the Delhi Sultanate.
The city was initially named "Sultanpur" after the Sultan but later renamed "Jaunpur" in memory of his cousin, Muhammad bin Tughluq, whose given name was Jauna Khan.
Situated on the banks of the Gomti River, Jaunpur offered a central position within Firoz Shah Tughlaq's expanding territories, facilitating control over the eastern regions.
