Which pair consists entirely of major minerals?

Explanation:
Major minerals (macrominerals) are those needed in larger amounts, typically more than 100 mg per day. They include calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur. The pair that consists entirely of major minerals is calcium and sodium. Calcium supports bones and teeth and has other roles in signaling; sodium helps regulate extracellular fluid balance and is important for nerve impulses and muscle activity. The other options mix minerals that are generally classified as trace minerals (such as iron, copper, and boron), which are required in smaller amounts. Therefore, calcium and sodium form the pair composed entirely of major minerals.
