Consider the following statements about rancidity of fats /oils
I.it is an oxidation process
II.It can be prevented by adding BHA
III.its degree is not measured as RM value
IV.its degree is measured as iodine value
Choose the correct option

Options

A. I and IV
B. I,Iiand IV
C. I,II and III
D. II and III

Answer

To solve the question regarding the statements about rancidity of fats and oils, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement I: It is an oxidation process.**
- Rancidity is indeed an oxidation process. When fats and oils are exposed to air, they undergo oxidation, leading to the formation of off-flavors and odors. Therefore, this statement is **True**.

2. **Statement II: It can be prevented by adding BHA.**
- BHA (Butylated Hydroxyanisole) is a synthetic antioxidant that is commonly used to prevent the oxidation of fats and oils. It helps in preserving the quality of food by preventing rancidity. Thus, this statement is also **True**.

3. **Statement III: Its degree is not measured as RM value.**
- The degree of rancidity is not measured using the RM (Rancidity Measurement) value. Instead, rancidity is often assessed through sensory evaluation or other methods, but RM value is not one of them. Therefore, this statement is **True**.

4. **Statement IV: Its degree is measured as iodine value.**
- The iodine value is a measure of the degree of unsaturation of fats and oils, not a direct measure of rancidity. While unsaturated fats can be more prone to rancidity, the iodine value itself does not measure rancidity directly. Hence, this statement is **False**.

### Conclusion:
Based on the analysis:
- Statements I, II, and III are True.
- Statement IV is False.

Thus, the correct option includes statements I, II, and III.

### Final Answer:
The correct option is: **I, II, and III are true.**
