Answer: Option (c) is the correct answer.
Step-by-step explanation:
When a compound is broken down into smaller pieces and then these pieces are dissolved into a solution then the particles are scattered throughout the solution. This process is known as dispersion.
Dissociation is a process in which a compound when dissolved in an aqueous solution dissociates into two different atoms or molecules.
Ionization is a process in which a compound when dissolved in an aqueous solution forms ions.
Condensation is a process in which vapors or gaseous phase converts into liquid state.
Hence, we can conclude that the process of dissolving by breaking into smaller pieces is called dispersion.
