How much elemental iron does Ferrous Sulfate contain?

12%
20%
33%
100%

The correct answer is: 20%

Ferrous Sulfate is an iron supplement used to treat or prevent iron deficiency anemia. The "elemental iron" refers to the amount of iron that is actually absorbed by the body. Ferrous Sulfate contains 20% elemental iron, which is why B is the correct answer. Option A (12%) and C (33%) are incorrect because they do not accurately reflect the amount of iron that is actually absorbed by the body. Option D (100%) is incorrect because not all of the iron in Ferrous Sulfate is absorbed, so it does not contain 100% elemental iron.
