Solution
The correct option is B Amylopectin Polysaccharides contain a large number of monosaccharide units joined together by glycosidic linkages. Theseare the most commonly encountered carbohydrates in nature. Amylopectin is insoluble in water and constitutes about 80-85% of starch. It is a branched chain polymer of alpha-D-glucose units in which chain is formed by C1−C4 glycosidic linkage whereas branching occurs by C1−C6 glycosidic linkage.
Hence option (b) is correct.
