In the following disaccharide
1 ring (A) is pyranose with $\alpha$-glycosidic link
2 ring (A) is furanose with $\alpha$-glycosidic link
3 ring (B) is pyranose with $\beta$-glycosidic link.
4 ring (B) is furanose with $\alpha$ - glycosidic link.
Explanation:
The six memembered cyclic structure of glucose is called pyranose structure $(\alpha$ and $\beta)$ in analogy. Pyranose is cyclic organic compound with one oxygen and five carbon atom in the ring. Hence ring $\mathrm{I}$ is Pyranose with $\alpha$-glycosidic bond linkage which means oxide linkage which connect monasaccharide unit in polysaccharide below the plane so, option (a) is correct.

Identify the correct statement about the following pairs of compounds.
1 $\mathrm{A}$ and $\mathrm{B}$ diastereomers, $\mathrm{C}$ and $\mathrm{D}$ distereomers
2 $\mathrm{A}$ and $\mathrm{B}$ enantiomers, $\mathrm{C}$ and $\mathrm{D}$ diastereomers
3 $\mathrm{A}$ and $\mathrm{B}$ diastereomers, $\mathrm{C}$ and $\mathrm{D}$ enantiomers
4 $\mathrm{A}$ and $\mathrm{B}$ enantiomers, $\mathrm{C}$ and $\mathrm{D}$ enantiomers
Explanation:
In the absence of stereo center in A and B these are diastereoisomer it is also not mirror image of each other. Both $\mathrm{C}$ and $\mathrm{D}$ are mirror image so it is enantiomer.
