Explanation

Vitamins are classified into two categories based on their solubility: fat-soluble and water-soluble. Fat-soluble vitamins (A, D, E, and K) are stored in the liver and fatty tissues and are not easily excreted [t4][t5]. In contrast, water-soluble vitamins, which include the Vitamin B complex and Vitamin C (ascorbic acid), dissolve in water and are not stored in significant amounts in the body [t3][t8]. Consequently, any excess or unmetabolized amounts of these vitamins are filtered by the kidneys and excreted through the urine [t1][t5][t10]. While both Vitamin B and Vitamin C are water-soluble and excreted in urine, Vitamin C is the most prominent single vitamin often cited in this context because it is rapidly eliminated once saturation occurs [t1][t9]. In many standard competitive examinations, Vitamin C is the preferred answer when options are singular, though both B and C share this physiological pathway.
