Options

A. `CuSO_(4).5H_(2)O`
B. `CuI`
C. `[Cu(NH_(3))_(4)]SO_(4)`
D. `Cu(CH_(3)COO)_(2).Cu(OH)_(2)`

Explanation

To solve the question about Schweitzer's reagent used for dissolving cellulose in the manufacture of artificial silk, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Schweitzer's Reagent**:
- We need to determine what Schweitzer's reagent is. It is a chemical compound used in the process of dissolving cellulose.

2. **Chemical Composition**:
- The chemical formula for Schweitzer's reagent is \( \text{Cu(NH}_3\text{)}_4\text{SO}_4 \). This indicates that it contains copper (Cu), ammonia (NH₃), and sulfate (SO₄).

3. **Application**:
- Schweitzer's reagent is specifically used in the textile industry, particularly in the manufacture of artificial silk. It helps dissolve cellulose, allowing it to be processed into fibers.

4. **Conclusion**:
- Therefore, the answer to the question is that Schweitzer's reagent used for dissolving cellulose in the manufacture of artificial silk is \( \text{Cu(NH}_3\text{)}_4\text{SO}_4 \).

### Final Answer:
Schweitzer's reagent used for dissolving cellulose in the manufacture of artificial silk is \( \text{Cu(NH}_3\text{)}_4\text{SO}_4 \).
