Solution and Explanation

Starch is a polysaccharide made up of glucose units and consists of two main components: amylose and amylopectin. Amylose is a linear polymer of glucose, while amylopectin has a branched structure. On average, amylose makes up about 15-20% of starch, while the remaining 80-85% is amylopectin. 
Thus, the correct answer is \( \boxed{15-20\%} \), corresponding to option (E).
