The correct statement about the following disaccharide is-

Step-by-step solution

In the given structure, ring one I has one O -atom and is a 6 membered ring, thus is called pyranose ring, whereas ring II has one O -atom and is a five membered ring, thus is called furanose. The disaccharide is linked by a glycosidic bond between C - 1 of glucose (in the α -position, α linkage) and C - 2 of fructose (in the β -position, β -linkage).
