Solution

The correct option is B Glycogen
When two alpha D-glucose molecules join together a more commonly occurring isomer of glucose, form a glycosidic linkage, the term is known as a α-1,4-glycosidic bond. Glycogen is a readily mobilized storage form of glucose. It is a very large, branched polymer of glucose residues that can be broken down to yield glucose molecules when energy is needed. Most of the glucose residues in glycogen are linked by α-1,4-glycosidic bonds.
So, the correct answer is option B.
