The correct answer is option 4. Vitamin D.
Vitamin D is a fat-soluble vitamin, which means it dissolves in and can be absorbed by fat. Fat-soluble vitamins are typically absorbed along with dietary fats and are stored in the body's fatty tissues and liver. Here's a brief explanation of each option:
1. Vitamin C (Ascorbic Acid): Vitamin C is a water-soluble vitamin, meaning it dissolves in water. It is not stored in the body for long periods, and excess amounts are usually excreted in the urine.
2. Vitamin \(B_2\) (Riboflavin): Vitamin \(B_2\) is a water-soluble vitamin. Like vitamin C, it dissolves in water and is not stored in large amounts in the body. Excess amounts are excreted in the urine.
3. Vitamin \(B_4\): There is no recognized vitamin \(B_4\). The B-vitamin complex includes \(B_1\) (thiamine), \(B_2\) (riboflavin), \(B_3\) (niacin), \(B_5\) (pantothenic acid), \(B_6\) (pyridoxine), \(B_7\) (biotin), \(B_9\) (folate), and \(B_{12}\) (cobalamin), but not \(B_4\).
4. Vitamin D (Calciferol): Vitamin D is unique among the options as it is fat-soluble. It can be synthesized by the body when the skin is exposed to sunlight, and it is also obtained from certain foods or supplements. Vitamin D is crucial for the absorption of calcium and phosphorus in the intestines, playing a key role in bone health. It is stored in the liver and fatty tissues, allowing the body to use it when needed.
In summary, the fat-soluble vitamin in the options provided is Vitamin D. |
