The Bohr model for the spectra of a H-atom
A. will not be applicable to hydrogen in the molecular from.
B. will not be applicable as it is for a He-atom.
C. is valid only at room temperature.
D. predicts continuous as well as discrete spectral lines.
The correct answers are the options (a, b). The model of the atom proposed by Neil Bohr was applicable for the hydrogen atom and some other light atoms containing only one electron around the nucleus which is stationary having a positive charge, Ze (called a hydrogen-like atom, e.g., H, He+, Li+2, Na+1 etc). But one of the limitations of the model is that it is not applicable to hydrogen in its molecular form and also in case of He atom.
