Which polysaccharide in fiber may include resistant starch (RS)?

Cellulose
Glycogen
Inulin
Starch

The correct answer is: Cellulose

Cellulose is the correct answer because it is a type of fiber that can contain resistant starch (RS). Cellulose is a complex carbohydrate found in the cell walls of plants and is one of the main components of dietary fiber. Resistant starch refers to starch and starch degradation products that resist digestion in the small intestine and can have beneficial effects on health by acting as a prebiotic in the colon. Inulin, on the other hand, is a type of soluble fiber that acts as a prebiotic but is not a source of resistant starch. Starch, including glycogen, is a complex carbohydrate that is easily digestible and not considered a source of resistant starch.
