Solution
The correct options are
A Rutherford
C Bohr
D Planck
The atoms and molecules of any one chemical species emit and absorb light at wavelengths characteristic of that species. Thus emission and absorption spectra act like fingerprints, uniquely identifying the atom or molecule that produced them. By about 1870 spectroscopy had become a powerful tool of chemical analysis and had led to the discovery of several previously unknown elements. In particular, it was, and still is, the only way to determine the chemical composition of the sun, other stars, and interstellar matter.
So discovery of Blamer and Lyman series was made before all well known atomic models.
