B. Blast furnace
C. Both (a) and (b)
D. None of these

Answer

To solve the question regarding the self-reduction of `Cu2S` (copper sulfide) to copper, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Process**:
- Self-reduction involves the conversion of a metal sulfide (in this case, `Cu2S`) to the metal (copper) itself, often involving the formation of an intermediate oxide.

2. **Roasting of `Cu2S`**:
- The first step in the self-reduction process is roasting `Cu2S`. Roasting is a process where the ore is heated in the presence of oxygen, which leads to the oxidation of the sulfide.
- The reaction can be represented as:
\[ 2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2 \]
- Here, `Cu2S` is converted to `Cu2O` (copper(I) oxide) and sulfur dioxide (`SO2`).

3. **Self-Reduction Reaction**:
- The next step involves the self-reduction of `Cu2O` using `Cu2S`. This can be represented as:
\[ Cu_2O + Cu_2S \rightarrow 4Cu + SO_2 \]
- In this reaction, `Cu2O` is reduced by `Cu2S` to produce copper metal and sulfur dioxide.

4. **Equipment Used**:
- This self-reduction process is typically carried out in a Bessemer converter, which is a type of furnace used for the conversion of metal ores into pure metals.

5. **Final Answer**:
- Therefore, the self-reduction of `Cu2S` to copper can be carried out in a **Bessemer converter**.
