Answer 1

Hint:This is a mine owned by the HCL. This mine was started over 2,000 years ago and the deposit consists of two lodes: Madhan lode (footwall) & the Kudhan lode (hanging wall).

Complete answer:
Copper production in India is only about 2 percent of world copper production in view of its potential reserve limited to 2%. But in production we are still within the first 20 countries of the world and also one of its largest importers in line with China, Japan, South Korea and Germany. Hazaribagh ,Singhbham and Khetri are some of the famous copper mines of India. Now let's see the options:-
Zinc- Hindustan Zinc limited is the company which produces zinc in a country. The famous mines are located in Rajasthan and some are in Andhra Pradesh hence this is the incorrect option.
Steel- Steel is one of the most important industrial metals used in our country . India in its second year plan focused on setting up steel industries which has made India a major exporter of Steel in the world hence it is not the correct option.
Copper- HCL or Hindustan Copper Limited is the company for extracting the majority of copper in India . This mineral is found mainly in Rajasthan, Madhya Pradesh and in the Chotanagpur region . Khetri mines is one of the famous copper mines of India hence it is the correct option.
Aluminium- Aluminium is extracted from the bauxite ore and is not ready to Khetri mines thus it is the incorrect option .

Therefore, the correct answer is option C) Copper.

Note: Mining is done by both opencast and underground methods in India. The major copper mines are the Khetri copper belt in Rajasthan, Singhbhum copper belt in Jharkhand and Malanjkhand copper belt in Madhya Pradesh which are mined by HCL.
