Answer 1

Hint: Vitamins are a group of chemical substances which are required in the correct amount for the growth, development and proper functioning of the human body. There are 13 essential vitamins and their common names are based on English alphabets such as Vitamin A, Vitamin B, Vitamin C and Vitamin D. But each vitamin has its specific chemical name.

Complete answer:
All the vitamins are classified into two groups: Fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins are stored in the body's fatty tissue. If they get accumulated in excess, it may lead to hypervitaminosis. The fat-soluble vitamins are vitamins A, D, E, and K.
The water-soluble vitamins are not stored in the body. Excess water-soluble vitamins are excreted out of the body along with the urine. Although, the body keeps a small reserve of water-soluble vitamins. Vitamin B-complex and Vitamin C are water-soluble vitamins.
The chemical name for different vitamins are different for example Vitamin A as retinol, vitamin C is ascorbic acid, similarly, the chemical name of vitamin D is calciferol. It is also called ‘Sunshine vitamin” because vitamin D is made by our body after being in the Sun for 10 to 15 minutes thrice in a week. This is sufficient to make the body's requirement of vitamin D for most people living in a country where sunlight is sufficient.
Vitamin D plays an important role in calcium metabolism. It helps the body absorb calcium which is essential for the normal development and maintenance of healthy teeth and bones.

Thus, Option D. calciferol is the correct answer.

Note: Vitamins are essential nutrients for the human body to work properly and to stay healthy. Vitamins also strengthen our immune system. Most vitamins can be obtained from the food that we eat or from vitamin supplements.
