Disaccharides are which of the following?

Explanation:
Disaccharides are a type of carbohydrate formed when two monosaccharide units are joined by a glycosidic bond, typically through a dehydration synthesis reaction. This creates two-sugar molecules such as sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two glucose units). That’s why this option is the best match. The other choices point to different biomolecules: monosaccharides are single sugar units like glucose, fructose, and galactose; amino acids are the building blocks of proteins; and nucleotides are the building blocks of nucleic acids.
