Answer: Option A."Hydrolysis"
Explanation:
Polymers breaks down into monomers following hydrolysis reaction.
hydrolysis is a chemical reaction that occurs when a water molecule inserts across the bond.
In hydrolysis reactions, the polymer breaks or divide into two components one part that gains hydroxyl molecule (OH–) and the other part that gains gains a hydrogen atom (H+) due to split of water molecule.
Hence, the correct option is A.
