Squashes are stored by adding

Options

A. Citric acid
B. KCl
C. `Na_(2)SO_(3)`
D. Sodium metabisulphide

Answer

To solve the question of how squashes are stored, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Purpose of Storage**:
- The primary goal of storing squashes is to prevent spoilage and maintain their quality over time.

2. **Research Common Preservatives**:
- Various preservatives are used in food storage, but we need to identify one that is specifically effective for squashes.

3. **Identify the Effective Preservative**:
- Sodium Meta Bisulfite (Na2S2O5) is known to be used for preserving food, including squashes.

4. **Understand the Mechanism**:
- Sodium Meta Bisulfite releases sulfur dioxide (SO2) when it reacts. This gas acts as a preservative by killing bacteria and preventing decay.

5. **Conclusion**:
- Therefore, the correct answer to the question is that squashes are stored by adding Sodium Meta Bisulfite (Na2S2O5).

### Final Answer:
Squashes are stored by adding Sodium Meta Bisulfite (Na2S2O5).
