Question:

Answer the question on basis of passage given below:

Vitamins represent a group of organic compounds which are needed in small amount for the healthy growth and maintenance of our body. These are not synthesized by the body and are supplied in the diet. The deficiency of vitamins can be supplemented with medicines.

Which vitamins are water soluble?

Options:

Vitamin B and Vitamin C.

Vitamin C and Vitamin A.

Vitamin D and Vitamin K.

Vitamin B and Vitamin A.

Correct Answer:

Vitamin B and Vitamin C.

Explanation:

The correct answer is option 1. Vitamin B and Vitamin C.

Vitamins are essential micronutrients required by the body for various physiological functions, including metabolism, growth, and overall health. They are classified into two main categories based on their solubility: water-soluble and fat-soluble vitamins.

Water-soluble vitamins:

Vitamin B complex: This group includes several individual B vitamins, such as \(B_1\) (thiamine), \(B_2\) (riboflavin), \(B_3\) (niacin), \(B_5\) (pantothenic acid), \(B_6\) (pyridoxine), \(B_7\) (biotin), \(B_9\) (folic acid or folate), and \(B_{12}\) (cobalamin). These vitamins are water-soluble, meaning they dissolve in water. They are not stored in the body to a significant extent and are excreted through urine. Therefore, they need to be consumed regularly through the diet to maintain adequate levels in the body. These vitamins play crucial roles in energy metabolism, nerve function, red blood cell production, and DNA synthesis.

Vitamin C (ascorbic acid): Vitamin C is another water-soluble vitamin. Like the B vitamins, it dissolves in water and is excreted through urine. Vitamin C is known for its antioxidant properties, which help protect cells from damage caused by free radicals. It also plays a vital role in collagen synthesis, wound healing, immune function, and the absorption of iron from plant-based foods.
