The correct statement about the following disaccharide is-

In the given structure, ring one $\left(I\right)$ has one $O$-atom and is a $6$ membered ring, thus is called pyranose ring, whereas ring $\left(II\right)$ 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 $\alpha$ -position, $\alpha$ linkage)$and C - 2$~of fructose (in the $\beta$-position, $\beta$-linkage).
