The correct answer is: A. Sonipat
Sonipat is a city in Haryana, India. It is located in the northern part of the state, on the banks of the Yamuna River. Sonipat is an important historical city, and has been inhabited since the 6th century BCE. The city was ruled by the Tomara dynasty from the 7th to the 12th centuries, and then by the Mughals from the 16th to the 18th centuries. Sonipat was an important center of trade and commerce during the Mughal period.
Copper currency of Harshavardhana period has been found from Sonipat. Harshavardhana was an Indian emperor who ruled from 606 to 647 CE. He was the founder of the Vardhana dynasty, and his empire included much of northern India. Harshavardhana was a powerful and successful ruler, and he is considered to be one of the greatest emperors in Indian history.
The copper currency of Harshavardhana period that has been found from Sonipat is a valuable historical artifact. It provides evidence of the economic and political importance of Sonipat during the Harshavardhana period. The currency is also a reminder of the rich history of Haryana.
