Answer: Option (d) is the correct answer.
Explanation:
A process in which a compound in a chemical reaction results in the formation of ions is known as ionization.
Whereas dissociation is a process in which a compound divides into atoms, ions or radicals.
A chemical compound which when dissolved in a solution forms ions and thus, conducts electricity is known as electrolyte.
A chemical reaction in which a compound reacts or combines with water is known as hydration.
Therefore, we can conclude that ionization is the term which refers to the formation of ions as a result of a chemical reaction.
