Understand the definition of a disaccharide: A disaccharide is a carbohydrate composed of two monosaccharide units joined together by a glycosidic bond.
Recall that monosaccharides are the simplest form of carbohydrates, such as glucose or fructose, and serve as the building blocks for larger carbohydrates.
Visualize the structure of a disaccharide, such as sucrose or lactose, which consists of exactly two monosaccharide units chemically linked.
Note that the number of monosaccharide units in a disaccharide is always two, as the prefix 'di-' indicates two units.
Conclude that the correct answer to the question is based on the definition of a disaccharide, which contains two monosaccharide units.
