Answer

Correct option: A.

Equal to the number of branches plus one.

Glycogen is the multi branched polysaccharide of glucose units popularly known as animal starch, as it is chemically similar to starch.
It has $30,000$ glucose residues and a molecular weight of about $4.8$ million.
Glucose residues in glycogen are arranged in a highly branched bush like chains.
There are two main linkage patterns, observed in glycogen,
i.e., a $1-4$ linkage in the straight part and a $1-6$ linkage in the area of branching.
The distance between two branching points is $10-14$ glucose residues.
Glycogen has as many non$-$reducing endsas branches plus one.
