Question

The vitamin, which is generally may be excreted in urine by humans, is

• A. Vitamin C
• B. Vitamin K
• C. Vitamin A
• D. Vitamin E

Answer 1

The correct option is A Vitamin C

The two major classes of vitamins are fat soluble and water soluble. Vitamin C and all of the B vitamins - thiamine, riboflavin, niacin, vitamin B${}_6$, folate, vitamin B${}_{12}$, biotin and pantothenic acid share similar characteristics because they are all water soluble. The body has a limited ability to store these vitamins so they need to be continuously replenished by the diet. Water-soluble vitamins are absorbed by the digestive tract into the bloodstream, metabolized and then excreted by the kidneys in the urine. Therefore, the correct answer is option A.
