Which of the following is an example of a major mineral?

Copper
Calcium
Chromium
Fluoride

The correct answer is: Calcium

Calcium is categorized as a major mineral because it is essential in significant quantities for various physiological functions in the body. It plays a crucial role in building and maintaining strong bones and teeth, and it is involved in muscle function, blood clotting, and nerve transmission. Major minerals, also referred to as macro-minerals, are required in larger amounts (generally more than 100 mg per day), and calcium is one of the most abundant minerals found in the human body. In contrast, the other options represent trace or minor minerals. Copper, while important for various biochemical processes, is required in much smaller amounts compared to calcium. Chromium is also classified as a trace mineral that helps regulate blood sugar but is not required in large quantities. Fluoride, although beneficial for dental health, is again considered a trace mineral, needed in smaller doses than major minerals. Thus, calcium stands out as the correct example of a major mineral due to its quantity and essential functions in overall health.
