Answer

To answer the question regarding the major functions of Polyunsaturated Fatty Acids (PUFAs), we can break down the information step by step:

### Step-by-Step Solution:

1. **Definition of PUFA**:
- PUFA stands for Polyunsaturated Fatty Acids. These are fatty acids that contain more than one double bond in their carbon chain.

2. **Types of PUFAs**:
- There are different types of PUFAs, including omega-3 and omega-6 fatty acids. An example of an omega-6 fatty acid is arachidonic acid.

3. **Essential Fatty Acids**:
- PUFAs are important because they include essential fatty acids that the body cannot synthesize on its own and must be obtained through diet.

4. **Cholesterol Levels**:
- PUFAs play a significant role in lowering cholesterol levels, particularly low-density lipoprotein (LDL) cholesterol, which is known as "bad" cholesterol.

5. **Atherosclerosis Prevention**:
- By lowering cholesterol levels, PUFAs help prevent atherosclerosis, a condition characterized by the buildup of fats and cholesterol in the arteries, which can obstruct blood flow.

6. **Conclusion**:
- The major functions of PUFAs include supplying essential fatty acids, lowering cholesterol levels, and preventing atherosclerosis. Therefore, the correct answer to the question is "all of the above".

### Final Answer:
The major functions of PUFA are: supplying essential fatty acids, lowering cholesterol levels, and preventing atherosclerosis. Thus, the correct option is "all of the above".
