What is nutrient that is best derived through diet a-dairy b-water c-grains d-iron

D- iron

Explanation:

Iron, a substantial mineral for the functioning of the body that, when lacking, can lead to anemia and immune system dysfunctions. Studies lead us to think that both iron overload and deficiency result in harmful changes in the immune response, because iron is essential for the growth of microorganisms, but it also constitutes proteins necessary for the destruction of infectious substances. For this reason, we can consider that one of the most important nutrients derived from a diet is iron.
