Explanation:
Vitamin D is an essential nutrient required by the body to maintain its structure as vitamin D helps in the absorption of the calcium and phosphorus which are required in maintaining the bones.
The biosynthesis of vitamin D begins in the skin when the cholesterol, a precursor of the vitamin D gets activated by the Ultraviolet B of the sunlight.
