Which of the following vitamin is water soluble?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Vitamin C
Vitamins are grouped by their solubility in water or fat. Of the four options, only vitamin C is water soluble. Because it is lost in urine and not stored, it has to come regularly from the diet, for example from citrus fruits and amla.
Why the other options are incorrect
Option (1) Vitamin A — Incorrect. It is fat soluble and is stored in the liver; fish liver oil, carrots, butter and milk are its sources.
Option (2) Vitamin D — Incorrect. It is fat soluble; it is made in the skin on exposure to sunlight and is also found in fish and egg yolk.
Option (3) Vitamin K — Incorrect. It is fat soluble; it is needed for the clotting of blood and comes from green leafy vegetables.
