In a characteristic \( \mathrm{X} \) - ray spectra of some atom superimposed on continuous \( \mathrm{X} \) - ray spectra:
(A) \( \mathrm{P} \) represents \( \mathrm{K}_{\alpha} \) line
(B) \( \mathrm{Q} \) represents \( \mathrm{K}_{\beta} \) line
(C) \( \mathrm{Q} \) and \( \mathrm{P} \) represents \( \mathrm{K}_{\alpha} \) and \( \mathrm{K}_{\beta} \) lines respectively
(D) Relative positions of \( \mathrm{K}_{\alpha} \) and \( \mathrm{K}_{\beta} \) depend on the particular atom
\( \mathrm{P} \)
