Options

A. Argentite
B. Stibnite
C. Haematite
D. Bauxite

Explanation

To determine which of the following is an ore of silver, we can analyze the given options step by step:

1. **Identify the Options**: The options provided are Argentite, Stibnite, Hematite, and Bauxite.

2. **Analyze Argentite**:
- Argentite is a mineral that is known to be an ore of silver. The chemical formula for Argentite is Ag₂S, which indicates that it contains silver (Ag).
- The name "Argentite" itself is derived from "Argentum," which is the Latin word for silver.

3. **Analyze Stibnite**:
- Stibnite has the chemical formula Sb₂S₃. This mineral is actually an ore of Antimony (Sb), not silver.

4. **Analyze Hematite**:
- Hematite is known to be an ore of iron, with the chemical formula Fe₂O₃. It does not contain silver.

5. **Analyze Bauxite**:
- Bauxite is an ore of aluminum, with the chemical formula Al₂O₃. This mineral does not contain silver either.

6. **Conclusion**:
- Based on the analysis, the only mineral that is an ore of silver is Argentite (Ag₂S).

Thus, the correct answer is **Argentite**.
