Answer 1

Hint: 81 different major and minor minerals have their deposits in the state of Rajasthan. The state of Rajasthan has found to have the largest resource of minerals in the form of deposits. The state mainly produces copper, silver, zinc, lead, etc.

Complete answer:
India produces around two percent of the entire world’s copper turnout. The only states that produce ores of copper in the whole of India are the states of Rajasthan, Madhya Pradesh, and Jharkhand. The popular copper mines of Rajasthan are in Bhilwara, Udaipur, Anjani, Bedawal, Sirohi, Manipura, etc. The location of Khetri can be found at the coordinates of 27.98 degrees north and 75.8 degrees east. It is located at the foothills of the Aravali RangeIn the district of Jhunjhunu in Rajasthan, numerous rich reserves of copper were excavated. This district is well known for its copper project. The copper belt of Khetri spreads over an area of about eighty(80) kilometers. These mines have numerous deposits of copper and are very prospective for the mining industry of India. The practice of mining started in that area in the Mauryan age. Hence, the Khatri mines were very productive in the terms of output of resources. The district of Jaipur, Bikaner, and Nagpur of Rajasthan doesn’t have much availability and variety of copper as compared to the Khetri mines.
Therefore, the correct answer is Option (D).

Note: Khetri Nagar is synonymous with the name ‘copper’.The main ore found in the Khetri copper deposits is chalcopyrite. In the Khetri region, mineralization is of high grade and is thus an important copper reserve of the country.
