Options

A. Vitamin A
B. Vitamin B complex
C. Vitamin D
D. Vitamin E

Explanation

To determine which of the following is not a fat-soluble vitamin, we first need to understand the characteristics of fat-soluble and water-soluble vitamins.

### Step-by-Step Solution:

1. **Identify Fat-Soluble Vitamins**:
- Fat-soluble vitamins are vitamins that dissolve in fats and oils. They are stored in the body's fatty tissue and liver. The main fat-soluble vitamins are:
- Vitamin A
- Vitamin D
- Vitamin E
- Vitamin K

2. **Identify Water-Soluble Vitamins**:
- Water-soluble vitamins dissolve in water and are not stored in the body. They need to be consumed regularly. The B-complex vitamins (B1, B2, B3, B5, B6, B7, B9, B12) and Vitamin C are examples of water-soluble vitamins.

3. **Analyze the Options**:
- If the question provides options, we need to analyze each option to see if it falls under fat-soluble or water-soluble vitamins.
- Since we know that Vitamin B complex is a group of water-soluble vitamins, it does not belong to the fat-soluble category.

4. **Conclusion**:
- Based on the definitions and classifications, the vitamin that is not fat-soluble is Vitamin B complex.

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