$A.$ B-complex
$B.$ Vitamin A
$C.$Vitamin D
$D.$ Vitamin E

Answer 1

Hint – Here we will proceed by using the concept of Vitamins then by explaining the concept of water-soluble and fat-soluble vitamins we will get our answer.

Complete answer:

Vitamins can be categorised on the basis of their solubility. The two-kinds of vitamins are water-soluble and fat-soluble vitamins.
Water-soluble vitamins are that can easily dissolve in water and as a result, are easily absorbed into the tissues of the body and metabolized more quickly than fat-soluble vitamins. These vitamins dissolve in water when they are ingested, then go into the bloodstream. The body keeps what it needs at that time.
Fat-soluble vitamins dissolve in fat and can be stored in your liver and fatty tissues until needed. They wait around in your body fat until your body needs them.
Let us explain all the parts one by one.
(a). B-complex- B vitamins are a class of water- soluble vitamins. B vitamins play a vital role in maintaining good health and well-being. B vitamins tend to boost energy. Vitamin-B dissolves quickly in the body.
(b). Vitamin A – Fat-soluble vitamins are absorbed by fat globules within the body and then carried throughout the blood-stream. Vitamin A is one of the four fat-soluble vitamins.
( c). Vitamin D – Vitamin-D is one of the fat-soluble vitamins responsible for increasing calcium, magnesium and multiple other biological effects. In humans most important compounds are Vitamin D$_3$ and Vitamin D$_2$
(d). Vitamin E – A nutrient that the body needs in small amounts to stay healthy and work the way it should. It is fat-soluble and is found in seeds, nuts, etc. and vegetable oils. Vitamin E boosts the immune system.
From the above explanation it is clear that Vitamin B-complex (Vitamin B group) is a water-soluble vitamin. Vitamin A,D,E, are fat-soluble vitamins.
Therefore, A is the correct option.

Note – In order to solve such types of questions, we will try to explain all the parts one by one. By explanation, we will easily get our answer. Also, vitamin is an organic molecule that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism.
