The two classes of vitamins are ___________ soluble and __________ soluble.

Fat, protein
Protein, oil
Protein, water
Fat, water

The correct answer is: Fat, water

Vitamins are categorized into two main classes based on their solubility: fat-soluble and water-soluble vitamins. Fat-soluble vitamins are those that dissolve in fats and oils, which allows them to be stored in the body's fatty tissues and the liver. This group includes vitamins A, D, E, and K. Due to their solubility in fat, these vitamins can accumulate in the body, which means they must be consumed in moderation to avoid toxicity. On the other hand, water-soluble vitamins dissolve in water, which enables them to be absorbed directly into the bloodstream. This group includes the B vitamins and vitamin C. Because water-soluble vitamins aren't stored in significant amounts in the body, they need to be regularly consumed as excess amounts are typically excreted through urine. Thus, the correct answer reflects the classification of vitamins based on their solubility into fats and water, distinguishing how they are absorbed, stored, and utilized in the body.
