A. Vitamin C is water insoluble
B. Vitamin A is water soluble
C. Vitamin C cannot be stored in our body
D. Riboflavin is vitamin B?
Correct Answer: C. Vitamin C cannot be stored in our body.
Explanation
Vitamin C is a water-soluble vitamin, which means it dissolves in water and is not stored in large amounts inside the human body. Because of this property, any extra vitamin C taken through food is usually removed from the body through urine.
Due to this rapid removal, the body requires a regular supply of vitamin C from daily diet sources such as fruits and vegetables.
The other statements are incorrect because:
Vitamin C is water soluble, not water insoluble.
Vitamin A is a fat-soluble vitamin, so it dissolves in fats rather than water.
Riboflavin is vitamin B?, not vitamin B?.
Therefore, the correct statement is that vitamin C cannot be stored in the body for long periods, which is why it must be consumed regularly.
