Which ofthe following are fat soluble vitamins:

(A) vit A

(B) vit B

(C) vit D

(D) vit E

(E) vit K

Choose the correct answer from the options given below:

The correct option is (A), (C), (D) and (E) only.

Vitamins are essential organic compounds that our bodies need in small amounts to function properly. Based on their solubility behavior in different solvents, vitamins are broadly classified into two categories:
1. Fat-soluble vitamins: These vitamins dissolve in organic solvents and fats. They are absorbed along with dietary fats in the small intestine and can be stored in the body's fatty tissues and liver for future use. The vitamins that belong to this category are:
- Vitamin A (A)
- Vitamin D (C)
- Vitamin E (D)
- Vitamin K (E)
A helpful mnemonic to remember them is the word "ADEK".

2. Water-soluble vitamins: These vitamins dissolve easily in water. Unlike fat-soluble vitamins, they are not stored in the body for long periods (any excess is excreted through urine), so they need to be consumed regularly in our diet. The water-soluble vitamins include:
- Vitamin B-complex group (B)
- Vitamin C

Therefore, among the options given, Vitamin A (A), Vitamin D (C), Vitamin E (D), and Vitamin K (E) are fat-soluble, whereas Vitamin B (B) is water-soluble. This matches the option (A), (C), (D) and (E) only.
