Which of the following best lists the major dietary forms of carbohydrates and correctly states their general role in human nutrition?

Sugars, starch, and fiber; they provide energy (sugars and starch) and structural/fermentable components (fiber), with carbohydrates serving as a primary energy source.

Amino sugars, glycoproteins, and glycosaminoglycans; these are the dietary carbohydrate fractions responsible for providing the bulk of caloric energy in a typical diet.

Monounsaturated, polyunsaturated, and trans carbohydrates; they are primary sources of energy and are equivalent to sugars, starch, and fiber in digestion and metabolism.

Sterols, triglycerides, and phospholipids; they are the major carbohydrate forms that provide immediate glucose to cells and are broken down by glycolysis.
