Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

option A is correct Explanation:- ANSWER (A) ring (i) is pyranose with α-glycosidic link The six-membered cyclic structure of glucose is called pyranose structure (α−orβ−), in analogy with pyran which is a cyclic organic compound with one oxygen and five carbon atoms in the ring. Hence, ring (i) is pyranose. The ring (i) is pyranose with α-glycosidic linkage which means the oxide linkage which connects the monosaccharide units in polysaccharide below the plane.
