Correct answer: (c) 1 and 3
Explanation
- A
1 and 2
(a) 1 and 2. Iron ore–Ballari is correctly matched (Bellary–Hospet belt), so pairing 2 with 1 as both wrong is false.
- B
2 and 3
(b) 2 and 3. Ballari iron ore is right, so 2 should not be in the ‘not matched’ pair.
- C
1 and 3
(c) 1 and 3. Copper is not a Chitradurga speciality in the usual mineral map (copper is Khetri, Malanjkhand, Singhbhum). Manganese is not a Bhilwara speciality (Bhilwara is marble/zinc; manganese is Balaghat, Odisha, Karnataka). Those two mismatches are the official key. Iron–Ballari and bauxite–Katni stay as matched on this paper.
- D
2 and 4
(d) 2 and 4. Both Ballari iron and Katni bauxite are treated as matched here, so they are not the ‘NOT correctly matched’ pair.
Summary. Official key is (c). Copper–Chitradurga and manganese–Bhilwara are not correctly matched. Iron ore–Ballari and bauxite–Katni are the pairs that stand.
