Correct Answer is D
Explanation
Choice A reason: Fresh fruits are incorrect because they are not rich sources of iron. They are good sources of vitamin C, which can enhance iron absorption, but they do not provide enough iron by themselves.
Choice B reason: Milk and cheese are incorrect because they are not rich sources of iron. They are good sources of calcium, which is important for bone health, but they can interfere with iron absorption if consumed in excess.
Choice C reason: Whole grain breads are incorrect because they are not rich sources of iron. They are good sources of complex carbohydrates, which provide energy and fiber, but they contain phytates, which can inhibit iron absorption.
