The correct answer is: A. Palaeolithic culture
The Palaeolithic period is the earliest period of human history, lasting from approximately 2.5 million years ago to 10,000 years ago. It is also known as the Old Stone Age. During this time, humans were hunter-gatherers who lived in small groups. They used simple tools made of stone, bone, and wood.
The Chirand site is located in the Saran district of Bihar, India. It is a prehistoric site that has been dated to the Palaeolithic period. The site has yielded a number of stone tools, including hand axes, cleavers, and scrapers. These tools provide evidence that humans were living in the Chirand area at least 250,000 years ago.
The other options are incorrect because they are not associated with the Palaeolithic period. The Mesolithic period is the period between the Palaeolithic and Neolithic periods. It lasted from approximately 10,000 to 5,000 years ago. During this time, humans began to develop agriculture and live in larger settlements. The Neolithic period is the period when humans first began to practice agriculture. It lasted from approximately 5,000 to 3,000 years ago. During this time, humans also began to develop pottery and metalworking. The Chalcolithic period is the period when humans first began to use copper and bronze. It lasted from approximately 3,000 to 2,000 years ago.
