Final answer:
Oligosaccharides are polymers containing a small number of monosaccharides. Stachyose, raffinose, and amylose are all examples of oligosaccharides.
Step-by-step explanation:
Oligosaccharides are polymers containing a small number, typically three to ten of monosaccharides. They include dextrins, glycans linked to lipids or proteins, and other carbohydrates. Stachyose, raffinose, and amylose are all examples of oligosaccharides, so the correct answer is b. dried beans and peas.
