B. Carbonate and oxide ore of Zn
C. Oxide and sulphate or of Zn
D. Sulphate and sulphite gre of Zn

Answer

To solve the question regarding the classification of zincate and calamine, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Compounds**:
- Zincate is identified as ZnO.
- Calamine is identified as ZnCO3.

2. **Determine the Type of Ore for Zincate**:
- The chemical formula ZnO indicates that zincate is an oxide of zinc.
- Therefore, zincate is classified as an oxide ore.

3. **Determine the Type of Ore for Calamine**:
- The chemical formula ZnCO3 indicates that calamine is a carbonate of zinc.
- Therefore, calamine is classified as a carbonate ore.

4. **Summarize the Findings**:
- Based on the classifications, we conclude that zincate is an oxide ore and calamine is a carbonate ore.

5. **Select the Correct Option**:
- The correct option that describes zincate and calamine respectively is:
- Option 1: oxide and carbonate ore of zinc.

### Final Answer:
Zincate and calamine respectively are oxide and carbonate ore of zinc.
