Answer
Correct option: A.
Glucose
a
Starch is a polymer of glucose. It is formed by the attachment of glucose unit by glycosidic bonds. The basic formula of starch is $\left( C _6 H _{10} O _5\right) n$. It exists in two forms amylose and amylopectin. Amylose is formed by linkage of glucose by alpha $1,4$ glucose unit. It is a linear polymer. Amylopectin is a branched polymer of glucose where two polymeric chains of glucose of alpha $1,4$ glucose unit are linked by alpha $1,6$ linkage.
