C. β-1,4 glycosidic linkage

D. α-1,6 glycosidic linkage

📝 Explanation

Maltose is a reducing disaccharide formed from two D-glucose units linked by an α-1,4 glycosidic bond. The C1 of the first glucose (in α-configuration) is linked to the C4 of the second glucose. The second glucose retains a free anomeric carbon, making maltose a reducing sugar.
