Which of the following is a major mineral?

Explanation:
Major minerals are minerals required in larger amounts by the body, typically more than 100 mg per day. Calcium is a major mineral because it is needed in relatively large quantities and is essential for building and maintaining bones and teeth, as the mineral that gives bones their strength. It also plays key roles in muscle contraction, nerve transmission, blood clotting, and various enzyme and signaling activities. In contrast, iron, zinc, and iodine are trace minerals, required in smaller amounts: iron for oxygen transport in hemoglobin, zinc for immune function and enzyme activity, and iodine for thyroid hormone synthesis. This is why calcium is categorized as a major mineral.
