Answer 1

Correct Answer: Iron

Rationale:

Milk is a highly nutritious liquid that is a rich source of many essential nutrients, including calcium, protein, vitamins, and fats. However, it is notably deficient in iron.
Iron is a critical mineral for the body, as it is a key component of hemoglobin, which carries oxygen in the blood. A deficiency in iron can lead to conditions such as anemia, characterized by fatigue and weakness.
Infants and young children who consume large amounts of milk without sufficient iron intake from other sources are at risk of developing iron deficiency.

Explanation of Other Options:

Phosphorus

Rationale: Milk is a good source of phosphorus, which is essential for the formation of bones and teeth. Phosphorus also plays a significant role in how the body uses carbohydrates and fats.

Sodium

Rationale: Milk contains sodium, which is important for maintaining fluid balance, nerve transmission, and muscle function. Although not very high, the sodium content in milk is sufficient for its nutritional role.

Potassium

Rationale: Milk is a good source of potassium, which helps to maintain proper heart function and regulate blood pressure. Potassium is also important for muscle function and nerve transmission.

Conclusion:

Among the given options, milk is deficient in iron. While it contains other essential minerals such as phosphorus, sodium, and potassium, it lacks sufficient iron, making it necessary to obtain this mineral from other dietary sources.
