Answer

To determine which of the following is not a fat-soluble vitamin, we need to classify the vitamins into two groups: fat-soluble vitamins and water-soluble vitamins.

### Step-by-Step Solution:

1. **Understand Vitamin Classification**: Vitamins are classified into two main categories: fat-soluble vitamins and water-soluble vitamins.

2. **Identify Fat-Soluble Vitamins**: The fat-soluble vitamins include:
- Vitamin A
- Vitamin D
- Vitamin E
- Vitamin K

3. **Identify Water-Soluble Vitamins**: The water-soluble vitamins include:
- Vitamin C
- Vitamin B complex (which includes B1, B2, B3, B5, B6, B7, B9, and B12)

4. **Analyze the Options**: Given the options, we need to identify which vitamin does not belong to the fat-soluble category. The options likely include a mix of fat-soluble and water-soluble vitamins.

5. **Select the Correct Answer**: Since Vitamin B complex is classified as a water-soluble vitamin, it is the vitamin that is not fat-soluble.

### Final Answer:
The vitamin that is not a fat-soluble vitamin is **Vitamin B complex**.
