Which one among the following is a water soluble vitamin ?

Vitamins are essential organic compounds classified into two categories based on their solubility: fat-soluble and water-soluble. Fat-soluble vitamins include Vitamin A, D, E, and K [t1][t2]. These vitamins dissolve in fats and oils, are absorbed along with dietary fats, and can be stored in the body's liver and fatty tissues for long-term use [t1][t3]. In contrast, water-soluble vitamins include Vitamin C (ascorbic acid) and the entire B-complex group [t6][t7]. These vitamins dissolve in water and are directly absorbed into the bloodstream [t1]. Unlike fat-soluble vitamins, the body cannot store significant amounts of water-soluble vitamins; any excess is typically excreted through urine, necessitating a regular daily intake through diet [t3][t6]. Therefore, among the given options, Vitamin C is the only water-soluble vitamin, while Vitamins A, E, and K are fat-soluble.
