To protect them from corrosion.
(II) They protect their flavours.
(III) Tp protect them from being rancid .
(IV) To protect their taste. Which of the following statements are correct ?

Options

A. (II), (III) ,(IV)
B. (III) and (IV)
C. only (III)
D. (I) and (II)

Explanation

To determine which statements regarding the flushing of packed food items made up of oils and fats with inert gas are correct, let's analyze each statement step by step.

1. **Understanding the Purpose of Inert Gas**:
- Packed food items containing oils and fats are often flushed with inert gases like nitrogen. This is primarily done to prevent oxidation, which can lead to rancidity.

2. **Analyzing Each Statement**:
- **(I) They protect them from corrosion**:
- This statement is incorrect. Corrosion typically refers to the deterioration of metals, not oils and fats. The inert gas does not serve the purpose of preventing corrosion in this context.

- **(II) They protect their flavours**:
- This statement is correct. By flushing with inert gas, the oxidation process is minimized, which helps in preserving the flavors of the food.

- **(III) They protect them from being rancid**:
- This statement is also correct. The inert gas prevents the oxidation of oils and fats, which is the primary cause of rancidity.

- **(IV) To protect their taste**:
- This statement is correct as well. Similar to the preservation of flavors, preventing oxidation also helps in maintaining the overall taste of the food.

3. **Conclusion**:
- The correct statements are (II), (III), and (IV). The first statement (I) is incorrect.

### Final Answer:
The correct statements are:
- (II) They protect their flavours.
- (III) They protect them from being rancid.
- (IV) To protect their taste.
