A polymer is a
A
small molecule
B
macromolecule
C
biomolecule
D
large molecule made out of small subunits
Explanation: 

Detailed explanation-1: -Most large biological molecules are polymers, long chains made up of repeating molecular subunits, or building blocks, called monomers. If you think of a monomer as being like a bead, then you can think of a polymer as being like a necklace, a series of beads strung together.

Detailed explanation-2: -Polymers are very large molecules compared to water. They have many more atoms than a water molecule–from 10, 000 to 100, 000 atoms per molecule. The word polymer is derived from the Greek root poly-, meaning many, and mer, meaning part or segment.

Detailed explanation-3: -Monomer-Small organic molecules which can act as subunits which bind together to form larger molecules called polymers. Monosaccharide-A carbohydrate that consists of a single sugar subunit. Examples of monosaccharides include ribose, deoxyribose, glucose, fructose, galactose, and many others.
