A
Starch is a single molecule with a complex structure.
B
Starch is a simple sugar that forms a crystalline structure.
C
Starch is made up of various types of monomers.
D

Verified step by step guidance
1
Understand the definition of a polymer: A polymer is a large molecule composed of repeating structural units, typically connected by covalent chemical bonds.
Identify the monomer unit in starch: Starch is primarily composed of glucose units.
Recognize the structure of starch: Starch is a polysaccharide, which means it is a carbohydrate polymer made up of many glucose monomers.
Examine the linkage in starch: The glucose units in starch are linked together by glycosidic bonds, forming a long chain.
Conclude why starch is a polymer: Since starch consists of repeating glucose units linked by glycosidic bonds, it fits the definition of a polymer.
