Rutherford inferred the existence of a dense, positively charged nucleus based on results of a scattering experiment.
Explanation
Bohr proposed a planetary model of the atom to explain the emission spectrum of hydrogen. Hence option B is incorrect.
Einstein explained the observation of the photoelectric effect experiment by stating that light has particle-like properties. Hence option C is incorrect.
Schrödinger proposed that electrons have wave like nature. Hence option D is incorrect.
