💡 Solution & Explanation

Hydrolysis requires a galactosidase, showing that galactose and mannose are linked by a galactosidic linkage. For sugar to be reducing, one of the hexoses must have free hemiacetal form. The methylation /hydrolysis procedure shows the point of attachment of the glycosidic bond to mannose. C1 is anomeric carbon on mannose ring and both    forms satisfy the above conditions.
