Quizplus · Accepted Answer

Dietary fibers are mainly provided by plant cell walls, which are composed of complex carbohydrates such as cellulose, hemicellulose, and pectin. These carbohydrates are not digested in the human small intestine and instead pass into the large intestine where they provide important health benefits.

 Plant gums, such as guar gum, xanthan gum, and carrageenan, are also sources of dietary fiber. These gums are often used as food additives to improve texture or as thickeners in processed foods. Like other types of dietary fiber, plant gums are not digested in the small intestine and contribute to digestive health.

Therefore, both B and D are the best choices.
