Which one of the following is not a Harappan site?

Sohgaura is not a Harappan site but a Mauryan-era location in Uttar Pradesh, famous for a copper plate inscription detailing famine relief measures. While Kot Diji and Chanhudaro are prominent sites in Pakistan and Desalpur is a known Harappan settlement in Gujarat, Sohgaura belongs to a much later chronological period. This question tests the ability to geographically and chronologically distinguish between Indus Valley Civilization sites and those belonging to later historical periods like the Mauryan Empire.
