B. `{:(a,b,c,d),(1,2,3,4):}`
C. `{:(a,b,c,d),(2,3,4,1):}`
D. `{:(a,b,c,d),(3,4,1,2):}`

Explanation

To solve the problem of matching List I with List II, we will analyze each item in List I and identify its corresponding item in List II based on the chemical composition and classification of the ores.

### Step-by-Step Solution:

1. **Identify Argentite**:
- Argentite has the chemical formula Ag₂S, which indicates that it is a sulfide ore of silver.
- **Match**: Argentite (a) → Sulfide ore of silver (4)

2. **Identify Cuprite**:
- Cuprite has the chemical formula Cu₂O, which indicates that it is an oxide ore of copper.
- **Match**: Cuprite (b) → Oxide ore of copper (3)

3. **Identify Siderite**:
- Siderite has the chemical formula FeCO₃, which indicates that it is a carbonate ore of iron.
- **Match**: Siderite (c) → Carbonate ore of iron (2)

4. **Identify Carnallite**:
- Carnallite has the chemical formula KCl·MgCl₂·6H₂O, which indicates that it is a halide ore of magnesium.
- **Match**: Carnallite (d) → Halide ore of magnesium (1)

### Final Matches:
- a → 4 (Argentite → Sulfide ore of silver)
- b → 3 (Cuprite → Oxide ore of copper)
- c → 2 (Siderite → Carbonate ore of iron)
- d → 1 (Carnallite → Halide ore of magnesium)

### Conclusion:
The correct matching is:
- (a) Argentite → (4)
- (b) Cuprite → (3)
- (c) Siderite → (2)
- (d) Carnallite → (1)

Thus, the correct code is **1**.
