The word . . . . . . . . on a label means that a product contains no amount of, or only trivial or 'physiologically inconsequential' amounts of, one or more of these components: fat, saturated fat, cholesterol, sodium, sugar and calories.

Answer: Option C

Labeling Term "Free": The word "free" on a label means that a product contains no amount of, or only trivial or "physiologically inconsequential" amounts of, one or more of these components: fat, saturated fat, cholesterol, sodium, sugar, and calories.

Other Options:

Option A: low - Indicates that the product contains a small amount of a particular component, but not zero.

Option B: lean - Usually refers to meat products with a limited amount of fat.

Option D: reduced - Means that the product has at least 25% less of a particular component compared to the regular product.

Therefore, the word "free" on a label indicates no amount or only trivial amounts of the specified components.
