Solution
The correct option is A peptization
The phenomenon of converting a freshly precipitated mass into colloidal state by the action of solute or solvent is known as peptization.
In biochemistry, dialysis is the process of separating molecules in solution by the difference in their rates of diffusion through a semi-permeable membrane, such as dialysis tubing.
Dissolution is the process by which a solute forms a solution in a solvent. The solute, in the case of solids, has its crystalline structure disintegrated as separate ions, atoms and molecules form.
Hence, option A is the correct answer.
