(A) Conductivity decreases with dilution for strong electrolyte as well as weak electrolyte. (B) On dilution, The number of ions per unit volume that carry current in a solution decreases. (C) Molar conductivity increases with dilution. (D) Molar conductivity of strong electrolyte follows DHO equation but it is not applicable for weak electrolyte. (E) On dilution degree of dissociation of weak electrolyte increases. So answer is (A), (C) & (D)
