The correct answer is: A. Sonipat.
Sonipat is a city in the Indian state of Haryana. It is located in the Sonipat district, which is one of the 22 districts of Haryana. The city is located on the banks of the Yamuna River, about 30 kilometers (19 mi) north of Delhi. Sonipat is an important industrial and commercial center. It is also a major transportation hub, with a railway station and an airport.
The city has a long history. It was founded in the 6th century BCE by the Tomara dynasty. Sonipat was an important center of trade and commerce during the Gupta period (320-550 CE). The city was also a major center of learning during this time.
Sonipat was ruled by the Tomara dynasty until the 12th century CE. The city was then ruled by the Chauhans, the Tomaras, and the Mughals. In the 18th century CE, Sonipat was ruled by the Marathas. The city was then ruled by the British East India Company from 1803 to 1947.
After India’s independence in 1947, Sonipat became a part of the Indian state of Haryana. The city has since grown rapidly and is now one of the major cities in Haryana.
Copper currency of Harsha period has been found from Sonipat. Harsha was an Indian emperor who ruled from 606 to 647 CE. He was the founder of the Harsha Empire, which included most of northern India. Harsha was a great patron of art and literature. He was also a devout Buddhist.
The copper currency of Harsha period is made of copper and is inscribed with the name of Harsha. The currency is a valuable historical artifact. It provides evidence of the economic and political power of Harsha’s empire.
The other options are incorrect because copper currency of Harsha period has not been found from those places.
