Which of the following is a major mineral?

Explanation:
Major minerals are nutrients the body needs in larger amounts, typically more than about 100 mg per day. Sodium fits this category because it plays essential roles in maintaining fluid balance, transmitting nerve impulses, and supporting muscle function, requiring relatively higher daily intake. In contrast, minerals like iron, zinc, and copper are needed in smaller amounts and are classified as trace minerals, tied to more specific functions such as oxygen transport (iron) and enzyme activity (zinc and copper). So sodium is identified as a major mineral due to its substantial daily requirement and broad physiological roles.
