Correct option: B.
The atoms of the source
b
(b) In line spectrum, bright coloured lines are observed on a dark background. These are called spectral lines. Each spectral line has a definite wavelength. Line spectrum is obtained per gases and metallic vapours, when they are in the atomic state. It means that line spectrum is related with the atomic state of matter.
