The occurrence of dark lines (Fraunhofer lines) in the observed emission spectrum of the sun suggests:
a) that the composition of the sun lacks certain elements.
b) that there is no emission of certain frequencies because relaxation does not occur.
c) that the excitation energy available is discontinuous and limited.
d) that absorption of certain frequencies is occurring at some location between the emitter and the observer.
