B. 1 and 2 are correct
C. 2 and 4 are correct
D. 1 and 3 are correct

Answer

To determine which of the following are fat-soluble vitamins, we need to identify each vitamin's classification based on its solubility.

1. **Identify the Vitamins**:
- **Retinol**: This is known as Vitamin A.
- **Calciferol**: This is known as Vitamin D.
- **Tocopherol**: This is known as Vitamin E.
- **Riboflavin**: This is known as Vitamin B2.

2. **Classify Each Vitamin**:
- **Fat-Soluble Vitamins**: These include Vitamins A, D, E, and K. They are soluble in fats and oils.
- **Water-Soluble Vitamins**: These include the B-complex vitamins (like Riboflavin) and Vitamin C. They dissolve in water.

3. **Check Each Option**:
- **Retinol (Vitamin A)**: Fat-soluble.
- **Calciferol (Vitamin D)**: Fat-soluble.
- **Tocopherol (Vitamin E)**: Fat-soluble.
- **Riboflavin (Vitamin B2)**: Water-soluble.

4. **Conclusion**:
The fat-soluble vitamins from the options provided are:
- Retinol (Vitamin A)
- Calciferol (Vitamin D)
- Tocopherol (Vitamin E)

Thus, the correct answer is options (1), (2), and (3).
