D. A 1, B 2, C 3, D 4

Answer

To solve the problem of matching the compounds given in (X) with their respective uses in (Y), we will analyze each compound and identify its use step by step.

### Step-by-Step Solution:

1. **Identify Compound A: NaOH**
- NaOH is known as sodium hydroxide or caustic soda.
- It is primarily used in the process of saponification, which is the production of soap.
- **Match**: A (NaOH) → 4 (Soap)

2. **Identify Compound B: Na₂S₂O₃**
- Na₂S₂O₃ is sodium thiosulfate.
- It is commonly used as an antichlor, which is a substance that neutralizes chlorine in bleaching processes.
- **Match**: B (Na₂S₂O₃) → 3 (Antichlor)

3. **Identify Compound C: NaCN**
- NaCN is sodium cyanide.
- It is used as a germicide, which is a substance that kills harmful microorganisms.
- **Match**: C (NaCN) → 2 (Germicide)

4. **Identify Compound D: Na₂CO₃**
- Na₂CO₃ is sodium carbonate.
- It is used in the glass industry to lower the melting point of silica, which is essential in glass production.
- **Match**: D (Na₂CO₃) → 1 (Glass)

### Final Matching:
- A → 4 (Soap)
- B → 3 (Antichlor)
- C → 2 (Germicide)
- D → 1 (Glass)

### Codes:
The final codes for the matches are:
- A - 4
- B - 3
- C - 2
- D - 1
