The correct answer is A. Rajgir.
Gupta period coins have been found from many places in India, but Rajgir is one of the most important sites. Coins have been found in excavations at the site of the ancient city of Rajgir, which was the capital of the Gupta Empire. The coins found at Rajgir are a valuable source of information about the Gupta period, as they provide insights into the economy, society, and culture of the time.
The coins found at Rajgir are made of a variety of metals, including gold, silver, and copper. They are inscribed with a variety of symbols and images, including the names of Gupta kings, the names of their wives, and religious symbols. The coins provide evidence of the Gupta Empire’s extensive trade network, as they have been found in places as far away as Central Asia and the Middle East.
The coins found at Rajgir are a valuable resource for historians and archaeologists, as they provide insights into a period of Indian history that is not well-documented. The coins help to fill in the gaps in our knowledge of the Gupta period, and they provide a glimpse into the lives of the people who lived during that time.
The other options are incorrect because they are not places where Gupta period coins have been found.
