Which of the following lists contains only the seven major minerals defined by the >100 mg/day cutoff?

Sodium, iron, zinc, phosphorus, chloride, magnesium, manganese — because iron and zinc are often discussed and phosphorus is chemically similar in function to those other elements listed, so they fit the major category by association.

Calcium, iodine, selenium, magnesium, potassium, fluoride, sulfur — since these elements all contribute to metabolic reactions in small amounts.

Phosphorus, chloride, copper, sodium, sulfur, chromium, calcium — because copper and chromium are commonly included as primary dietary minerals.
