Solution

The correct option is B Ionization
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions. It does not split like in dissociation reaction.
Therefore, $H_{2} O \to H^{+} + {O H}^{-}$ is an ionization reaction.
