The correct answer is B. Mitathal.
The Hakra culture was an early agricultural culture that flourished in the northwestern Indian subcontinent from about 3300 to 1900 BCE. The culture is named after the Hakra River, which is now a dry riverbed that runs through Pakistan.
The first excavated site of the Hakra culture was Mitathal, which is located in the Hisar district of Haryana, India. Mitathal was a large settlement with a population of several thousand people. The people of Mitathal lived in mud-brick houses and practiced agriculture. They also made pottery, tools, and weapons.
The Hakra culture was a significant development in the history of the Indian subcontinent. It was the first time that people in this region had developed a complex society based on agriculture. The Hakra culture also played an important role in the development of the Indus Valley Civilization.
The other options are incorrect. Kunal is a site of the Indus Valley Civilization, while Bhirrana is a site of the Early Harappan culture. None of these sites are associated with the Hakra culture.
