Question

Choose the correct group of fat-soluble vitamins.

• A. Cholecalciferol, $\alpha$-Tocopherol, Menadione
• B. Thiamine, Cholecalciferol, $\alpha$-Tocopherol
• C. Niacin, $\alpha$-Tocopherol, Menadione
• D. Biotin, Thiamin, Niacin

Hint:

Remember: Fat-soluble = ADEK. All other vitamins are water-soluble.

Answer 1

The Correct Option is A

Step 1: Recall classification of vitamins.
- Fat-soluble vitamins: A, D, E, K. - Water-soluble vitamins: B-complex, C.
Step 2: Match options with correct category.
- Cholecalciferol = Vitamin D (fat-soluble). - $\alpha$-Tocopherol = Vitamin E (fat-soluble). - Menadione = Vitamin K$_3$ (fat-soluble). Thus option (A) includes only fat-soluble vitamins. - Option (B): Thiamine = Vitamin B$_1$ (water-soluble). - Option (C): Niacin = Vitamin B$_3$ (water-soluble). - Option (D): Biotin = Vitamin B$_7$, Thiamine = B$_1$, Niacin = B$_3$ → all water-soluble.
Step 3: Conclude.
Only option (A) contains exclusively fat-soluble vitamins. Final Answer: \[ \boxed{\text{(A) Cholecalciferol, $\alpha$-Tocopherol, Menadione}} \]
