Which mineral is NOT a major mineral?

Explanation:
Major minerals are needed in relatively large amounts each day (roughly 100 mg or more) and include sodium, calcium, phosphorus, potassium, magnesium, chloride, and sulfur. Iron is classified as a trace mineral, meaning it’s required in much smaller amounts. Yet iron remains essential for carrying oxygen in the blood and for many enzyme functions, so its importance isn’t about quantity but about necessity at a lower intake. Because iron is a trace mineral, it is not a major mineral, while the other minerals listed are.
