Match List-I (Ores) with List-II (States where they are mined): A. Manganese · B. Nickel · C. Lead-zinc · D. Asbestos — 1. Madhya Pradesh · 2. Orissa · 3. Rajasthan · 4. Andhra Pradesh

Answer: (c) A - l; B- 2; C - 3; D - 4

Manganese – MP · nickel – Odisha · lead-zinc – Rajasthan · asbestos – Andhra.

The idea

A mining belt is defined by its rocks and ore deposits rather than by one isolated town. Several States may share the same mineral, so a matching question asks for a recognised association. One reliable pair can narrow the options without claiming that the mineral occurs only there.

Why the others are wrong

(a) Gives nickel to Rajasthan.

(b) Gives manganese to Andhra.

(d) Gives manganese to Andhra.

The trap

Lead-zinc–Rajasthan (Zawar) is the sure pair.

Elimination technique

Lead–zinc must match Rajasthan, which leaves (a) and (c). Nickel–Odisha separates them without relying on a production ranking.

Balaghat connects Madhya Pradesh’s manganese belt with the Nagpur–Bhandara belt in Maharashtra. Zawar and Rampura Agucha are Rajasthan lead–zinc anchors. Sukinda associates nickel with chromite; asbestos refers to fibrous minerals whose dust is harmful to health.
