A carbohydrate formed by two monosaccharide units is called a ...

Explanation:
The concept here is how carbohydrates are categorized by the number of sugar units. A carbohydrate formed by two monosaccharide units is a disaccharide. Monosaccharides are single sugar molecules, while disaccharides arise when two of these sugars join together via a glycosidic bond through dehydration synthesis. They can be hydrolyzed back into two monosaccharides, example sugars being maltose, sucrose, and lactose. Oligosaccharides are short chains of a few sugars (more than two but not many), and polysaccharides are long polymers of many sugar units. So the two-unit product fits the term disaccharide.
