The correct option is E Solvation
Solvation is solute-solvent interaction. It stabilizes solute in the solution. The solute particles ( ions/ molecules) are surrounded by solvent molecules.
For example, when common salt (NaCl) is dissolved in water, each Na+ is surrounded by several water molecules and each Cl− is surrounded by several water molecules. The interactions between the ions of NaCl (solute) and water (solvent) are ion-dipole interactions.
