Response:
B)Solvation 
Electrolytes are classified based on solvation of a  molecule in water and their solubulity in water.
Rules  for solubulity..
  • All compounds containing alkali metal ions, ammonium (NH4+), nitrate (NO3–), or acetate (CH3CO2– or C2H3O2–) ions are soluble.
  • All compounds containing halide ions except salt of Ag+, Cu+, Hg22+, or Pb2+ are soluble.
  • All compounds containing sulfate (SO42–) ion except salts of Ba2+, Ca2+, Hg2+, Pb2+, and Sr2+ are soluble.
  • Ba(OH)2, Ca(OH)2, and Sr(OH)2 are soluble
