Which reaction joins monosaccharides to form disaccharides?

Explanation:
Dehydration synthesis drives the joining of monosaccharides to make disaccharides. In this condensation reaction, a water molecule is removed as a glycosidic bond forms between two sugar units, linking them into a larger carbohydrate. This is the reverse of hydrolysis, which uses water to break the bond. Oxidation changes electrons or adds oxygen without creating a bond between sugars, and isomerization rearranges atoms within a molecule rather than linking two units.
