Water-soluble vitamins are those that dissolve in water and are not stored in the body. Instead, they are easily excreted through urine, which means they need to be consumed regularly in the diet. Vitamins B and C are classified as water-soluble vitamins.

Vitamin B encompasses a group of several distinct vitamins (such as B1, B2, B3, B6, B12, etc.) that play vital roles in energy metabolism and the functioning of the nervous system. Vitamin C is essential for the synthesis of collagen, antioxidant activity, and plays a critical role in immune function.

In contrast, the other options consist of fat-soluble vitamins, which are stored in the body's fatty tissue and liver. Vitamins A, D, E, and K (listed in the first option) are examples of fat-soluble vitamins, as are those mentioned in options C and D, which are not recognized as vitamins in the standard classifications of human nutrition. This understanding is crucial for grasping how different vitamins function and their impacts on health.
