The correct answer is: Molecular weight of polymers rises throughout the reaction.
The process of condensation polymerization takes place in the following manner.

A + B → Condense A - B Monomers Dimer

A−B+A → Condense A−B−A

A−B−A+B→A−B−A−B

In this process no initiator is required and it is also called step growth polymerization.
