Explanation
A. disaccharide: These are "double sugars" (like sucrose) that must be broken down further into single units before absorption.
B. monosaccharide: This is the simplest form of sugar (like glucose). The digestive system breaks all complex carbs down into monosaccharides so they can be absorbed into the bloodstream.
