Explanation:

Isolated remains of Homo erectus found in Hathnora in the Narmada Valley indicate that Madhya Pradesh might have been inhabited in the Middle Pleistocene era. Painted pottery dated to the later mesolithic period has been found in the Bhimbetka rock shelters. Chalcolithic sites belonging to Kayatha culture (2100–1800 BCE) and Malwa culture (1700–1500 BCE) have been discovered in the western part of the state.

The first statement is correct because the Paleolithic Phase is characterized by the use of stone tools made of flakes mainly scrapers, borers and blade-like tools. Second statement also correct but third statement is wrong because the evidence of early hunter-gatherers was found in Narmada Valley.
