New DelhiMatch List-I with List-II and select the correct answer using the codes given below the lists.

1. A

   4 2 3 1

   (a) 4 2 3 1. This code would send ONGC to New Delhi (4) but then pair MECL with Hyderabad (2). MECL headquarters is Nagpur, not Hyderabad, so the second limb already fails.

2. B

   1 2 4 3

   (b) 1 2 4 3. Starts ONGC at Bhubaneswar. NALCO sits in Bhubaneswar; ONGC’s listed HQ in this table is New Delhi. The opening pair is therefore wrong.

3. C

   4 3 2 1

   (c) 4 3 2 1. Official key. ONGC — New Delhi (4); Mineral Exploration Corporation Ltd. — Nagpur (3); NMDC — Hyderabad (2); NALCO — Bhubaneswar (1). That is the stored matching for this Set D row.

4. D

   2 3 4 1

   (d) 2 3 4 1. Opens ONGC with Hyderabad, which is NMDC’s city in this list, not ONGC’s.

Summary. Official key is (c) 4 3 2 1. The item matches four public mineral/energy agencies to headquarters. NALCO is the Bhubaneswar pair; NMDC is Hyderabad; MECL is Nagpur; ONGC is given as New Delhi in this paper. Codes that park ONGC in Odisha or NMDC’s city fail at the first letter. Honour the stored letter (c).
