B Correct answer
Explanation

Vitamin A is fat-soluble, meaning it dissolves in lipids and can be stored in body fat and the liver. Water-soluble vitamins (C and B-complex including riboflavin) dissolve in water, are not stored significantly, and excess is excreted in urine. This distinction is important for both absorption and toxicity considerations.
