Match the items given in column-I with that in column-II column-I (I) Fool's gold (II) Corundum (III) Diaspore (IV) Calamine column-II
(a)Al_2O_3 (b) Sulphide ore (c)ZnCO_3 (d)Al_2O_3H_2O (e) Sulphide of zinc

Options

A. I(c), II(d), III(a), IV(e)
B. I(b), II(a), III(d), IV(c)
C. I(e), II(d), III(a), IV(c)
D. I(d), II(c), III(b), IV(a)

Answer

To solve the matching question between column-I and column-II, we will analyze each item in column-I and find its corresponding item in column-II.

### Step-by-Step Solution:

1. **Identify Fool's Gold**:
- Fool's gold is commonly known as pyrite, which is a sulfide mineral.
- The chemical formula for pyrite is FeS₂, which classifies it as a sulfide ore.
- **Match**: Fool's gold (I) → Sulphide ore (b).

2. **Identify Corundum**:
- Corundum is an aluminum oxide mineral.
- The chemical formula for corundum is Al₂O₃.
- **Match**: Corundum (II) → Al₂O₃ (a).

3. **Identify Diaspore**:
- Diaspore is a mineral that consists of aluminum oxide combined with water.
- Its chemical formula is Al₂O₃·H₂O.
- **Match**: Diaspore (III) → Al₂O₃H₂O (d).

4. **Identify Calamine**:
- Calamine is primarily known as zinc carbonate.
- The chemical formula for calamine is ZnCO₃.
- **Match**: Calamine (IV) → ZnCO₃ (c).

### Final Matches:
- (I) Fool's gold → (b) Sulphide ore
- (II) Corundum → (a) Al₂O₃
- (III) Diaspore → (d) Al₂O₃H₂O
- (IV) Calamine → (c) ZnCO₃

### Summary of Matches:
- I - b
- II - a
- III - d
- IV - c
