The correct answer is: C) Hundreds of thousands of years.
The prehistory of Karnataka spans over hundreds of thousands of years. The earliest evidence of human habitation in Karnataka dates back to the Lower Paleolithic period, around 250,000 years ago. During this time, humans were hunter-gatherers who lived in small groups. The Middle Paleolithic period, from 100,000 to 40,000 years ago, saw the development of stone tools and the emergence of more complex social structures. The Upper Paleolithic period, from 40,000 to 10,000 years ago, was a time of great change, as humans began to domesticate animals and plants. The Neolithic period, from 10,000 to 5,000 years ago, saw the development of agriculture and the rise of the first civilizations.
The prehistory of Karnataka is a fascinating and complex topic. There is still much that we do not know about this period, but the research that has been done so far has revealed a rich and vibrant history.
