Water-soluble vitamins: a. often result in toxicities b. are easily excreted in the urine c. are stored in body tissues to a large extent d. are soluble in body fluids but insoluble in cooking water e. are not damaged by heat or oxygen exposure

Answer: Option (b) is the correct answer.

Explanation:

Vitamins which are soluble in water are known as water-soluble vitamins. And, vitamins which remain insoluble in water are known as water-insoluble vitamins.

Water-soluble vitamins are able to be easily excreted by the human body through urine. For example, vitamin C and vitamin B-complex are water soluble vitamins.

Thus, we can conclude that water-soluble vitamins are easily excreted in the urine.
