During silver plating of an article using potassium argentocyanide as electrolyte , the anode material should be [Cu , Ag , Pt , Fe]

Explanation

To determine the appropriate anode material for silver plating using potassium argentocyanide as an electrolyte, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Process of Electrolysis**:
- Electrolysis involves the use of an electric current to drive a non-spontaneous chemical reaction. In the case of silver plating, we need to deposit silver onto an article.

2. **Identify the Electrolyte**:
