The correct option is b
Step-by-step explanation:
Polymerization is a process in which many simple units (called monomers) are linked/joined together to form a giant molecule (called polymer). There are some polymers that occur naturally; for example starch and cellulose. Cellulose and glucose are made up of glucose monomers (although they contain different number and types of the glucose monomers).
While polymerization is also used industrially for the production of polythene, plastics and hoses.
