Option c is the correct answer Patliputra is not an Indus Valley site. Pataliputra adjacent to modern-day Patna was a city in ancient India, originally built by Magadha ruler Ajatashatru in 490 BCE, as a small fort near the Ganges river. Udayin laid the foundation of the city of Pataliputra at the confluence of two rivers, the Son and the Ganges. The other sites Kalibangan, Ropar and Lothal belongs to Indus Valley civilization.
