RAS question
The Khetri Copper Complex, one of India's largest copper producing units, is located in which district?
Correct answer: (C) Jhunjhunu.
The Khetri Copper Complex is located in Jhunjhunu district, Rajasthan.
Explanation
Khetri Copper Complex is in Jhunjhunu district, in Rajasthan's Shekhawati region. Hindustan Copper Limited's official Plants and Offices page lists Khetri Copper Complex with the address P.O. Khetri Nagar, District Jhunjhunu, Rajasthan. That official address establishes Jhunjhunu as the correct district, not a neighbouring district. The complex lies on the copper belt running from Khetri to Singhana and is operated by Hindustan Copper Limited as one of India's major copper mine and smelter units. For RAS, the key recall point is the district-location pairing: Khetri Copper Complex - Jhunjhunu.
Why the other options are wrong
- (A) Sikar is adjacent to the Khetri area, but Hindustan Copper Limited lists Khetri Copper Complex in District Jhunjhunu.
- (B) Churu lies to the west and is not the district named in the official address of Khetri Copper Complex.
- (D) Alwar may be associated with other mineral locations, but it is not where Hindustan Copper Limited places the Khetri Copper Complex.
Concept
This tests Rajasthan economic geography, especially the district-wise location of mineral-based industrial units. Such pairings recur in RAS because mines, smelters and industrial complexes are standard map-and-resource facts.
