Match List I with List II and select the correct answer using the codes given below the lists:

List I (Minerals)	List II (Mining area)
I. Graphite	(A) Bellary
II. Lead	(B) Didwana
III. Salt	(C) Rampa
IV. Iron Ore	(D) Zawar

Options:
A) I-C, II-D, III-B, IV-A
B) I-A, II-D, III-B, IV-C
C) I-C, II-A, III-D, IV-B
D) I-B, II-C, III-A, IV-D

To solve this matching correctly, we look at the specific mineral deposits associated with each region:

• Graphite is found in the Rampa area of Andhra Pradesh.
• Lead (and zinc) is concentrated in the Zawar mines of Rajasthan.
• Salt is commercially produced from the saltwater lake at Didwana, Rajasthan.
• Iron Ore (or Manganese) is the hallmark of the Bellary-Hospet region in Karnataka.

By matching these correctly: I-C, II-D, III-B, and IV-A. In the original 1998 question, the fourth mineral was Silver, which also comes from Zawar, creating a conflict in the mining area list that was only resolvable by choosing the option with the strongest specific matches (Graphite and Lead).
