Match List I with List II. List-I (Name of ore/mineral) (a) Calamine (b) Malachite (c) Siderite (d) Sphalerite List-II (Chemical formula) (i) ZnS (ii) FeCO3 (iii) ZnCO3 (iv) CuCO3, Cu(OH)2 Choose the most appropriate answer from the options given below

1. (a) → (iii), (b) → (iv), (c) → (ii), (d) → (i)
2. (a) → (iii), (b) → (iv), (c) → (i), (d) → (ii)
3. (a) → (iv), (b) → (iii), (c) → (ii), (d) → (i)
4. (a) → (iii), (b) → (i), (c) → (iv), (d) → (i)

Correct answer: (a) → (iii), (b) → (i), (c) → (iv), (d) → (i)

Solution

The correct option accurately matches each mineral with its corresponding chemical formula: Calamine is zinc carbonate (ZnCO3), Malachite is a copper carbonate hydroxide (CuCO3, Cu(OH)2), Siderite is iron carbonate (FeCO3), and Sphalerite is zinc sulfide (ZnS). This alignment reflects the correct chemical composition of each mineral.
