Which among the following is a fat-soluble vitamin?

The correct answer is Option (1) → Vitamin A

Vitamins are grouped by what they dissolve in, which decides how the body absorbs and stores them:

• Fat-soluble — A, D, E and K; absorbed with fats and stored in the liver and fatty tissue

• Water-soluble — the B group (B₂, B₁₂ and others) and C; not stored for long, and the excess leaves the body in urine

So Vitamin A is the fat-soluble vitamin among the options.
