Correct answer · Option 3
A-(IV), B-(II), C-(III), D-(I)
Explanation
Lattice enthalpy corresponds to dissociation into gaseous ions (A-IV). Sublimation of Na gives gaseous atoms, so atomization is B-II. Enthalpy of solution equals lattice plus hydration enthalpy (C-III). Dilution involves adding solvent to a solution (D-I).
