Answer

Two molecules of the same or one molecule each of two different monosaccharides.

Explanation:

A disaccharide on hydrolysis gives two molecules of the same or one molecule each of two different monosaccharides since a disaccharide is defined as the sugar formed by the glycosidic linkage of 2 monosaccharides.

Consider, for example, maltose. It hydrolyses to give 2 molecules of glucose.
