J Thompson who discovered the electron.Rutherford discovered the nucleus of his experiment the gold foil and postulated the nuclear model of the atom.Due to the failure of Rutherford's atomic model could not explain the stability of the substance,the postulate of Bohr's atomic model as given Rutherford in a modification of the form and assigned energy levels to electrons.Therefore the correct answer to this question is Dalton
