Statement I ; Spectrum produced by inert gases is always a line spectrum because inert gases exist as atoms only;

Statement II ; Absorption spectrum is always a discontinuous spectrum ;

White light is passed through a chemical substance. The chemical substance absorbs certain wavelengths of light and the transmitted light when passed through a prism always produces a discontinuous spectrum because some wavelengths of light are missing ;

Thus Absorption spectrum is always a discontinuous spectrum.
