Solution:
Amylose:
Amylose is a linear polymer made up of D-glucose units.
The glucose units are linked together by α−1,4-glycosidic bonds.
Amylopectin:
Amylopectin is a branched polymer of D-glucose units.
The linear chains are formed by α−1,4-glycosidic bonds.
Branching occurs due to α−1,6-glycosidic bonds at intervals.
Cellulose:
Cellulose is a linear polymer of D-glucose units.
The glucose units are linked by β-1,4-glycosidic bonds. This type of linkage gives cellulose its rigid, structural properties.
Now, let's match List-I (Glycosidic linkage) with List-II (Polysaccharide):
(A) α−1,4 : This linkage is characteristic of the linear chains in both amylose and amylopectin. Since amylose only has α−1,4 linkages for its main structure, it's the most direct match here. So, A - (I) Amylose.
(B) β-1,4: This linkage is unique to (III) Cellulose among the given options. So, B - (III) Cellulose.
(C) α−1,4,α−1,6 : The presence of both α−1,4 and α−1,6 linkages indicates a branched polysaccharide with alpha linkages, which is characteristic of (II) Amylopectin. So, C - (II) Amylopectin.
