Verified step by step guidance

Understand the concept of trace minerals: Trace minerals are essential nutrients that the body needs in very small amounts. They play various roles in maintaining health, including enzyme function and hormone production.

Identify common trace minerals: Some well-known trace minerals include iron, zinc, copper, manganese, iodine, selenium, and chromium.

Differentiate between trace minerals and major minerals: Major minerals, such as calcium, phosphorus, sodium, potassium, and chlorine, are required in larger amounts by the body compared to trace minerals.

Recognize that chromium is a trace mineral: Chromium is involved in the metabolism of carbohydrates, fats, and proteins, and it enhances the action of insulin.

Conclude that among the given options, chromium is the trace mineral, while phosphorus, sodium, chlorine, and potassium are considered major minerals.
