Question

Fat soluble vitamins are : 
A. Vitamin B\( _1 \) 
B. Vitamin C 
C. Vitamin E 
D. Vitamin B\( _{12} \) 
E. Vitamin K 
Choose the correct answer from the options given below :

• A. C and D Only
• B. A and B Only
• C. B and C Only
• D. C and E Only

Hint:

Remember the acronym "ADEK" to easily recall the fat-soluble vitamins: Vitamin A, Vitamin D, Vitamin E, and Vitamin K. All other vitamins are generally water-soluble.

Answer 1

The Correct Option is D

To determine which vitamins are fat-soluble, let's first understand the characteristics of fat-soluble and water-soluble vitamins.

• Fat-Soluble Vitamins: These vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. They include Vitamin A, D, E, and K.
• Water-Soluble Vitamins: These are not stored in the body and must be consumed more regularly. They include Vitamin B-complex (e.g., B₁, B₂, B₁₂, etc.) and Vitamin C.

In the given options:

• Vitamin E is a fat-soluble vitamin.
• Vitamin K is also a fat-soluble vitamin.
• Vitamin B₁ and B₁₂: Both are water-soluble vitamins.
• Vitamin C: This is a water-soluble vitamin.

Hence, the correct answer is C and E Only which corresponds to Vitamin E and Vitamin K, both of which are fat-soluble.

Conclusion: Vitamins that are fat-soluble can be stored in the body and include Vitamins A, D, E, and K. Among the options provided, only Vitamin E and Vitamin K are fat-soluble.

Answer 2

Fat-soluble vitamins are vitamins that dissolve in fats and oils and can be stored in the body's fatty tissues and liver. 
The fat-soluble vitamins are Vitamin A, Vitamin D, Vitamin E, and Vitamin K. 
Looking at the options provided in the question: A. Vitamin B\( _1 \) (Thiamine) is a water-soluble vitamin. B. 
Vitamin C (Ascorbic acid) is a water-soluble vitamin. C. 
Vitamin E (Tocopherol) is a fat-soluble vitamin. D. Vitamin B\( _{12} \) (Cobalamin) is a water-soluble vitamin. E. 
Vitamin K (Phylloquinone) is a fat-soluble vitamin. 
Therefore, the fat-soluble vitamins from the given list are Vitamin E (C) and Vitamin K (E). 
The correct answer is the option that includes only C and E.
