The correct answer is: A.Polymers are broken down into monomers.

Explanation:

Hydrolysis is the chemical process by which a polymer is broken down into its monomer units. In this reaction, water is used to break the covalent bonds between monomers that make up the polymer.

During hydrolysis, a water molecule is added, breaking the bond between two monomers and resulting in the separation of the monomer units.

For example, when starch (a polymer of glucose) undergoes hydrolysis, it breaks down into individual glucose molecules.

Why the other options are incorrect:

B.Monomers are joined to form a polymer.

This describes condensation (or dehydration synthesis), not hy...
