RAS question
The Khetri Copper Complex is located in which district?
Correct answer: (C) Jhunjhunu.
The Khetri Copper Complex is located at Khetri Nagar in Jhunjhunu district, Rajasthan.
Explanation
Jhunjhunu is correct because Hindustan Copper Limited's official Plants & Offices page lists the Khetri Copper Complex at P.O. Khetri Nagar, District Jhunjhunu, Rajasthan. Khetri Copper Complex is one of India's major copper-producing units and is operated by Hindustan Copper Limited. Khetri is important not only as a place name but also for its administrative location in Jhunjhunu district. For RAS, Rajasthan's mineral-industry geography commonly requires pairing a major industrial unit with its district, and the relevant pairing is Khetri Copper Complex-Jhunjhunu.
Why the other options are wrong
- (A) Sikar is wrong because the official Hindustan Copper Limited listing places Khetri Copper Complex in Jhunjhunu district, not Sikar.
- (B) Nagaur is wrong because Nagaur is linked with Makrana marble, while the Khetri Copper Complex is in Jhunjhunu.
- (D) Alwar is wrong because its mineral deposits are separate from the Khetri Copper Complex, which is officially placed under Jhunjhunu district.
Concept
Rajasthan's mineral-based industrial geography includes district-location mapping of major units. In RAS preparation, copper, marble and other minerals remain standard static-GK anchors for Rajasthan economy and geography.
