The correct answer is: Lower Paleolithic.
The Lower Paleolithic is the earliest period of the Stone Age, lasting from approximately 2.5 million to 300,000 years ago. It is characterized by the use of simple stone tools, such as hand axes and choppers. The earliest evidence of human habitation in Haryana dates back to the Lower Paleolithic period.
The Middle Paleolithic is the second period of the Stone Age, lasting from approximately 300,000 to 30,000 years ago. It is characterized by the use of more sophisticated stone tools, such as scrapers and points. The Middle Paleolithic period is not as well-represented in Haryana as the Lower Paleolithic period.
The Upper Paleolithic is the third period of the Stone Age, lasting from approximately 30,000 to 10,000 years ago. It is characterized by the use of even more sophisticated stone tools, such as needles and awls. The Upper Paleolithic period is also not as well-represented in Haryana as the Lower Paleolithic period.
The Neolithic is the final period of the Stone Age, lasting from approximately 10,000 to 4,500 years ago. It is characterized by the development of agriculture and the use of polished stone tools. The Neolithic period is not represented in Haryana at all.
In conclusion, the presence of Stone Age tools in Haryana indicates human habitation dating back to the Lower Paleolithic period.
