Question

Which of the following are fat soluble vitamins?
(A) Vitamin A
(B) Vitamin B
(C) Vitamin D
(D) Vitamin E
(E) Vitamin K
Choose the correct answer from the options given below:

• A. (A), (B), (D) and (E) only
• B. (A), (B), (C) and (D) only
• C. (A), (C), (D) and (E) only
• D. (B), (C), (D) and (E) only

Hint:

Remember the mnemonic: \[ \boxed{ADEK} \] These are the four fat-soluble vitamins. Vitamins B and C are water soluble.

Answer 1

The Correct Option is C

Concept: Vitamins are essential organic compounds required in small quantities for proper growth, metabolism and maintenance of body functions. Based on solubility, vitamins are classified into:
• Fat-soluble vitamins
• Water-soluble vitamins Fat-soluble vitamins: \[ A,\ D,\ E,\ K \] Water-soluble vitamins: \[ B \text{-complex and Vitamin } C \] Fat-soluble vitamins:
• Dissolve in fats and oils
• Are stored in liver and adipose tissues
• Can accumulate in body

Step 1: Identify Vitamin A.
Vitamin A: \[ \text{Retinol} \] is fat soluble. It is important for:
• Vision
• Healthy epithelial tissues Thus: \[ (A) \text{ is correct} \]

Step 2: Identify Vitamin B.
Vitamin B belongs to: \[ \text{Vitamin B-complex} \] These vitamins are water soluble. Therefore: \[ (B) \text{ is not fat soluble} \]

Step 3: Identify Vitamins D, E and K.

• Vitamin D helps calcium absorption.
• Vitamin E acts as antioxidant.
• Vitamin K is essential for blood clotting. All three are fat soluble vitamins. Thus: \[ (C),\ (D),\ (E) \] are correct.

Step 4: Select the correct combination.
Fat-soluble vitamins are: \[ A,\ D,\ E,\ K \] Hence correct combination is: \[ (A),\ (C),\ (D),\ (E) \] Therefore, the correct option is: \[ \boxed{(C)} \]
