Answer 1

Correct Answer - Option 4 : D

The correct answer is D.

• Vitamins are organic compounds that are required in small amounts in our diet but their deficiency causes specific diseases.
• Vitamins are designated by alphabets A, B, C, D, etc. Some of them are further named as sub-groups e.g. B1, B2, B6, B12, etc.
• Vitamins that are soluble in fat and oils but insoluble in water are kept in this group. These are vitamins A, D, E, and K.
• B group vitamins and vitamin C are soluble in water so they are grouped together.
• Vitamin D helps our body to use calcium for bones and teeth. Exposure to sunlight synthesizes Vitamin- D.
