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 Lower Paleolithic is also the time period when the first hominins, or early humans, evolved.
The presence of Stone Age tools in Haryana indicates that the area was inhabited by humans during the Lower Paleolithic. These tools have been found in a number of sites in Haryana, including the Soan Valley, the Narmada Valley, and the Thar Desert. The tools are made from a variety of materials, including flint, chert, and quartz. They are typically simple in form, and they were used for a variety of purposes, such as hunting, gathering, and butchering.
The discovery of Stone Age tools in Haryana provides important evidence for the early history of human habitation in the region. It suggests that humans have been living in Haryana for at least 2.5 million years. This is a significant finding, as it helps to fill in the gaps in our understanding of human evolution and migration.
The other options are incorrect because they refer to later periods in human history. The Middle Paleolithic lasted from approximately 300,000 to 30,000 years ago. The Upper Paleolithic lasted from approximately 30,000 to 10,000 years ago. The Neolithic lasted from approximately 10,000 to 4,500 years ago.
