Detailed Explanation:

The liver stores several vitamins essential for bodily functions.

Vitamin A is stored in large quantities (up to 2 years' supply) for vision, immunity, and cell growth.

Vitamin D is stored as calcifediol, regulating calcium absorption and bone health.

Vitamin B12 (cobalamin) is the only water-soluble vitamin significantly stored by the liver (up to 3–5 years' supply), supporting red blood cell formation and nerve function.

Vitamin C (ascorbic acid) is retained in smaller amounts for short-term use in collagen synthesis and immune function.

Thus, the liver stores vitamins A, B (especially B12), C, and D.
