Glycogen is branched chain polymer of $\alpha$ D-glucose units in which chain is formed by ${\mathrm{C}}_1\to {\mathrm{C}}_4$ glycosidic linkage whereas branching occurs by formation of ${\mathrm{C}}_1\to {\mathrm{C}}_6$ glycosidic linkage. Structure of glycogen is similar to

The structure of glycogen is

The structure of the given compound glycogen is similar to amylopectin and it is as follows

Based on the structure we can say that the structure of amylopectin is similar to that of glycogen i.e almost similar just lacks chain branching.

Hence option D is the correct answer.
