The Navdatoli archaeological site is considered to be associated with which river valley?

Correct answer: Narmada Valley

The governing concept is the geographical identification of Chalcolithic cultures and their archaeological sites. Navdatoli is located on the left bank of the Narmada River in present-day Madhya Pradesh and is widely associated with the Malwa cultural tradition. Thus option B, the Narmada Valley, is correct. The site is important for understanding settled farming, craft production, pottery, and copper-using communities of the Chalcolithic period. The Kaveri Valley belongs to a different regional setting, while the Brahmaputra Valley is in northeastern India and is not the location of Navdatoli. The Indus Valley is associated primarily with the Harappan civilisation and therefore is also an unsuitable answer. Remembering both “Navdatoli–Narmada” and “Malwa culture” helps avoid confusion.
