Answer #1

Both glycogen and starch are the polysaccharides of Glucose units. In starch, the linear chain glucose molecules are bound by alpha-1.4-glycosidic linkage whereas the branching points have alpha 1,6- glycosidic linkages.

In glycogen, the linear chain glucose molecules are bound by alpha-1.4-glycosidic linkage whereas the branching points have alpha 1,6- glycosidic linkages.

Therefore out of the given options, none is incorrect.

option e is correct.
