Explanation:
Polymerization reaction may be defined as the reactions in which large number of monomers are combined together to forms a large macro molecule. The small molecule like water is released during the reaction.
The single monomers unit joins to synthesize the new molecule. This reaction is also known as the synthesis reaction as the new molecule are synthesized in the reaction. The synthesis of biomolecules are also occur by the synthesis reaction.
Thus, the correct answer is option (a).
