The answer is letter A.
Iron is
an important nutrient that builds the composition of blood. It is necessary for
the delivery of oxygen through different parts of the body. Enzyme productions
also depend on the supply of iron and it is crucial in the total development of children who are
growing and developing hormones, neurotransmitters, and new cells within their
body. If iron stores are low, memory, mood, attention span, and focus are among
the effects of the deficiency because oxygen transport in the blood is lessened
or diminished. Iron comes from different sources of food and we cannot produce
this type of mineral in our body on our own.
