Match List – I with List – II and select the correct answer using the codes given below the lists. List – I (Mineral Exploration Agencies) A. Oil and Natural Gas Commission B. Mineral Exploration Corporation Ltd. C. National Mineral Development Corporation D. National Aluminium Company Limited List – II (Headquarters) 1. Bhubaneswar 2. Hyderabad 3. Nagpur 4. New Delhi Codes :
- (a)A-4 B-2 C-3 D-1
- (b)A-1 B-2 C-4 D-3
- (c)A-4 B-3 C-2 D-1
- (d)A-2 B-3 C-4 D-1
Correct — C, A-4 B-3 C-2 D-1. The four public-sector mineral/energy agencies map to their headquarters as: A. Oil and Natural Gas Corporation (ONGC) → New Delhi (4); B. Mineral Exploration Corporation Ltd. (MECL) → Nagpur (3); C. National Mineral Development Corporation (NMDC) → Hyderabad (2); D. National Aluminium Company Ltd. (NALCO) → Bhubaneswar (1). Three of these headquarters — MECL at Nagpur, NMDC at Hyderabad and NALCO at Bhubaneswar — are fixed and well known, which alone pins ONGC to the only remaining choice, New Delhi. ONGC's registered/corporate headquarters is in New Delhi (Deendayal Urja Bhawan, Vasant Kunj), although Dehradun remains a major operational and R&D centre for the corporation. That gives A-4 B-3 C-2 D-1 → option (c).
- (a)A-4 B-2 C-3 D-1 — Wrong — it swaps B and C. MECL is headquartered at Nagpur (not Hyderabad) and NMDC at Hyderabad (not Nagpur), so B-2/C-3 is incorrect.
- (b)A-1 B-2 C-4 D-3 — Wrong — almost every pair is misplaced: ONGC is not at Bhubaneswar, MECL not at Hyderabad, NMDC not at New Delhi and NALCO not at Nagpur.
- (d)A-2 B-3 C-4 D-1 — Wrong — MECL-Nagpur (B-3) and NALCO-Bhubaneswar (D-1) are right, but it puts ONGC at Hyderabad (A-2) and NMDC at New Delhi (C-4); ONGC is at New Delhi and NMDC at Hyderabad.
These are four Central Public Sector Enterprises tied to India's minerals and energy sector. ONGC (Oil and Natural Gas Corporation) is the maharatna oil and gas explorer; MECL (Mineral Exploration Corporation Ltd.) does detailed exploration and drilling of solid minerals under the Ministry of Mines; NMDC (National Mineral Development Corporation) is India's largest iron-ore producer; and NALCO (National Aluminium Company Ltd.) is an integrated bauxite-alumina-aluminium producer. Matching each to its headquarters city is a recurring UPPSC/UPSC 'organisation ↔ location' exercise.
The safe strategy in a match-list is to anchor on the pairs you are sure of and eliminate. Here MECL-Nagpur, NMDC-Hyderabad and NALCO-Bhubaneswar are the unambiguous anchors; each option must satisfy all three. Only option (c) does — A-4 B-3 C-2 D-1 — which automatically fixes ONGC at New Delhi. This avoids the ONGC-Dehradun confusion, since the other three headquarters already force the answer.
- MECL (Mineral Exploration Corporation Ltd.) — headquartered at Nagpur, under the Ministry of Mines.
- NMDC (National Mineral Development Corporation) — headquartered at Hyderabad; India's largest iron-ore producer.
- NALCO (National Aluminium Company Ltd.) — headquartered at Bhubaneswar, Odisha.
- ONGC's registered/corporate headquarters is New Delhi; Dehradun is a major operational/R&D base.
- Placing ONGC at Dehradun (a big operational centre) instead of its corporate HQ, New Delhi
- Interchanging MECL (Nagpur) and NMDC (Hyderabad)
UPPSC frequently asks 'organisation ↔ headquarters' match-lists for Indian PSUs — memorise NMDC-Hyderabad, NALCO-Bhubaneswar, MECL-Nagpur, MOIL-Nagpur, HCL-Kolkata.
Match List I with List II and select the correct answer using the codes given below the Lists: List I (Industrial Unit) I. Atlas Cycle Company Ltd. II. Bharat Earth Movers Ltd. III. Indian Farmers Fertilisers Cooperative Ltd. IV. National Aluminium Company Ltd. List II (Centre) A) Bangalore B) Bhubaneswar C) Kalol D) Sonepat Codes:
- (a) I-A, II-D, III-B, IV-C
- (b) I-A, II-D, III-C, IV-B
- (c) I-D, II-A, III-B, IV-C
- (d) I-D, II-A, III-C, IV-B
Answer(d) I-D, II-A, III-C, IV-B
Same concept — matching an Indian PSU/industrial unit to its city — and it directly overlaps on NALCO → Bhubaneswar (IV-B), the same pair tested in this UPPSC item.
