Correct answer: B. Cellulose

  • A. Starch
  • B. Cellulose
  • C. Glucose
  • D. Maltose

Explanation

The correct answer is cellulose. Cellulose is the most abundant carbohydrate because it is a key structural component in the cell walls of plants, giving them rigidity and strength. This makes it incredibly prevalent in the natural world. Starch is a storage carbohydrate and is not as widespread as cellulose. Glucose, while fundamental as a simple sugar, is not as abundant in its free form. Maltose is a disaccharide that is not as prevalent as cellulose.
