Match the entries of column I with appropriate entries of column II and choose the correct option but of the four options (a), (b), (c ), (d) given at the end of each question.
`{:(, "Column I",,,"Column II"), ((A), "Siderite",,(p),"Zinc"),((B),"Chalcocite",,(q),"Aluminium"),((C),"Calamine",,(r),"Copper"), ((D),"Bauxine",,(s),"Iron"):}`

Options

A. A-s, B- r, C-p, D-q
B. A-p, B-s, C-r, D-q
C. A-q, B-r, C-s, D-p
D. A-r, B-q, C-p,D-s

Answer

To solve the matching question between Column I and Column II, we need to identify the correct mineral or ore associated with each metal. Let's go through the entries step by step.

### Step-by-Step Solution:

1. **Identify the first entry in Column I:**
- **A) Siderite**
- Siderite is an iron ore.
- **Match:** A → s (Iron)

2. **Identify the second entry in Column I:**
- **B) Chalcocite**
- Chalcocite is a copper ore.
- **Match:** B → r (Copper)

3. **Identify the third entry in Column I:**
- **C) Calamine**
- Calamine is a zinc ore.
- **Match:** C → p (Zinc)

4. **Identify the fourth entry in Column I:**
- **D) Bauxite**
- Bauxite is an aluminum ore.
- **Match:** D → q (Aluminium)

### Final Matching:
- A → s (Iron)
- B → r (Copper)
- C → p (Zinc)
- D → q (Aluminium)

### Conclusion:
The correct matches are:
- A → s
- B → r
- C → p
- D → q

Thus, the correct option is **(a)**.
