2. Fat-soluble vitamins cannot be stored for later use.
3. Excess water-soluble vitamins are excreted in the urine.
4. Water-soluble vitamins can be toxic if stored in excess.
Correct Answer: 3

Rationale 2: Fat-soluble vitamins cannot be stored for later use is incorrect because they can be stored in large quantities in the liver and fat.
Rationale 3: Water-soluble vitamins are absorbed and readily dissolve in blood and body fluids, the excess of which is excreted in the urine. Because they are not stored to any significant degree, they must be ingested daily, otherwise deficiencies will quickly develop.

Because they are not stored to any significant degree, they must be ingested daily, otherwise deficiencies will quickly develop.
