B Correct answer
Explanation

Folic acid (vitamin B9) is part of the water-soluble B-complex vitamin group. Water-soluble vitamins dissolve in water and excess amounts are excreted in urine rather than stored. In contrast, vitamins A (retinol), D (calciferol), and K (phylloquinone) are fat-soluble and require dietary fats for absorption and are stored in body tissues.
