Which of the following vitamins is fat-soluble?

Vitamin D is a fat-soluble vitamin, meaning that it dissolves in fats and oils and can be stored in the body's fatty tissues and liver for later use. This classification allows it to be absorbed better when consumed with dietary fat. Fat-soluble vitamins, which include vitamins A, D, E, and K, play crucial roles in various bodily functions, such as bone health and immune function. In contrast, the other vitamins mentioned, such as Vitamin C and the B vitamins like B12, are water-soluble, which means they do not get stored in the body to the same extent and need to be consumed more regularly through diet.
