Concept:Maltose is a disaccharide formed by two D-glucose units joined through a glycosidic bond.Explanation:The glycosidic linkage in maltose connects the α-anomeric carbon (C1) of one glucose molecule to the C4 hydroxyl group of the other glucose molecule.This specific bond is called an α-(1→4) glycosidic linkage.Therefore, it is not α-(1→6) or β-(1→4).Answer:Option A: α‑1,4.
