Best Answer Explained in Below-:

The correct answer is C) iron, as milk is indeed a poor source of this essential mineral. While milk is widely recognized for its contributions to dietary calcium, protein, and certain vitamins (such as riboflavin and vitamin B12), it contains very little iron.

Iron is crucial for various bodily functions, including the production of hemoglobin, which carries oxygen in the blood. While dairy products can provide essential nutrients, they are not sufficient sources of iron compared to other food groups. For example, lean meats, legumes, and fortified cereals are significantly richer in iron.

In fact, the consumption of dairy products can inhibit iron absorption due to the presence of calcium and casein protein, which can bind to non-heme iron (the type of iron found in plant foods) and reduce its bioavailability. Therefore, while milk is nutritious and beneficial in many ways, it is not a reliable source of iron, making option C the correct choice in this context. For those needing increased iron intake, it is essential to include iron-rich foods in their diet alongside calcium sources like milk.
