Solution

The correct option is D Amylopectin
Amylopectin is a branched chain polymer of $α - D - g l u c o s e$ units in which chain is formed by $C_{1} - C_{4}$ glycosidic linkage whereas branching occurs by $C_{1} - C_{6}$ glycosidic linkage.
Thus, amylopectin contains linkage between $C_{1} a n d C_{4}$ and also between $C_{1} a n d C_{6}$ .
