This question refers to the passage and the chart.

Vitamins are nutrients that are needed for the normal metabolic functioning of the body. Vitamins dissolve in either fat or water. Excess fat-soluble vitamins can be stored in body fat. Excess water-soluble vitamins are excreted in the urine. For this reason, you should have regular sources of water-soluble vitamins in your diet.

Some people advise taking several times the recommended daily allowance of vitamins, called megadoses, to stay healthy. Which statement is the best summary of the risk of taking megadoses of vitamins?

^1. The water-soluble vitamins are excreted in urine, so megadoses are safe.

^2. Megadoses of fat-soluble vitamins are more likely to be harmful than megadoses of water-soluble vitamins.

^3. Vitamin D is fat soluble, but since it is added to milk, megadoses are not likely to reach toxic levels.

^4. The B vitamins are safe in megadoses because the benefits are greater than the disadvantages.

^5. Megadoses of vitamins are safe for individuals of normal weight and height who lack excess body fat.
