Which group of vitamins is classified as water soluble?

The correct classification of water-soluble vitamins includes those that dissolve in water and are not stored in significant amounts in the body. The B vitamin complex and vitamin C are prime examples of water-soluble vitamins.

Water-soluble vitamins play crucial roles in various bodily functions, including energy production, immune function, and the synthesis of neurotransmitters. Because these vitamins are not readily stored, they need to be consumed regularly in the diet, which underscores their importance in maintaining overall health and supporting physical activity.

In contrast, the other groups listed comprise primarily fat-soluble vitamins. Fat-soluble vitamins, including A, D, E, and K, are absorbed along with dietary fats and can be stored in the body's fatty tissues and liver. This characteristic differentiates them from water-soluble vitamins, which have different absorption, transportation, and excretion mechanisms.

Thus, option B accurately identifies the group of vitamins that are water-soluble, aligning with established nutritional science.
