The chemical reaction that breaks down a molecule by adding water is
A
Dehydration Synthesis
B
Hydrophobia
C
Hydrolysis
D
Dehydration
Explanation: 

Detailed explanation-1: -Literally, hydrolysis implies water reaction. It is a chemical mechanism in which, by adding a molecule of water, a molecule is broken into two pieces. As a salt with a weak acid or weak base (or both) is dissolved in water, the most common hydrolysis happens.

Detailed explanation-2: -Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro” = water and “lysis” = break) involves adding water to one large molecule to break it into multiple smaller molecules.

Detailed explanation-3: -Industrial Organic Chemistry In fact, Hydrolysis can be the reverse of a condensation reaction in which two molecules join together into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water.

Detailed explanation-4: -Hydrolysis (/haɪˈdrɒlɪsɪs/; from Ancient Greek hydro-‘water’, and lysis ‘to unbind’) is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile.

Detailed explanation-5: -: a chemical process of decomposition involving the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion of water.
