Detailed Solution

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

Inert gases like helium, neon, argon, krypton, xenon, and radon produce line spectra. This means they emit light at specific wavelengths, creating distinct lines in their spectrum.

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.
