Which of the following are macrominerals?

• A. Calcium, Phosphorus, Sodium, Chloride, Potassium, Magnesium, Sulfur
• B. Iron, zinc, manganese, iodine, copper
• C. Mg, Fe, Cu
• D. Sodium and potassium

Answer: (A)

Macrominerals are minerals needed in larger amounts by the body, typically more than about 100 mg per day, and the list includes calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur. The option that lists calcium, phosphorus, sodium, chloride, potassium, magnesium, and sulfur matches this set exactly. The other options show minerals that are considered trace minerals, required in smaller amounts: iron, zinc, manganese, iodine, copper. A mix like magnesium, iron, copper includes one macromineral with two trace minerals, so it isn’t the full group of macrominerals. A pair like sodium and potassium covers only two macrominerals and omits the rest. Therefore, the correct grouping is the one with all seven macrominerals.
