Which is a characteristic of condensation polymerization?

monomers are generally alkenes.
the reaction rarely produces a product.
each monomer has more than one functional group.
the polymer contains all the atoms in the monomer units.

The polymer contains all the atoms in the monomer units

Explanation:

Condensation polymerization is said to occur when two monomers combine with the loss of a small molecule such as water or HCl.

Condensation polymerization commonly occurs between having functional groups. A typical example of condensation polymers are carbohydrates, nylon 6,6 etc.

All the atoms in the individual monomers are usually represented in the polymer.
