The energy of a tungsten atom with a vacancy in \( L \) shell is \( 11.3 \mathrm{keV} \). Wavelength of \( K_{\alpha} \) photon for tungsten is \( 21.3 \mathrm{pm} \). If a potential difference of \( 62 \mathrm{kV} \) is applied across the \( x \)-rays tube following characteristic \( \mathrm{x} \) rays will be produced.
(A) \( K, L \) series
(B) Only \( K_{\alpha} \) and \( L \) series
(C) Only \( L \) series
(D) None
