A metal \((A)\) on heating in nitrogen gas gives compound \(B\). \(B\) on treatment with \(\mathrm{H}_{2} \mathrm{O}\) gives a colourless gas which when passed through \(\mathrm{CuSO}_{4}\) solution gives a dark blue-violet coloured solution. \(A\) and \(B\) respectively, are
- A \(\mathrm{Mg}\) and \(\mathrm{Mg}_{3} \mathrm{N}_{2}\)
- B \(Na\) and \(\mathrm{NaNO}_{3}\)
- C \(\mathrm{Mg}\) and \(\mathrm{Mg}\left(\mathrm{NO}_{3}\right)_{2}\)
- D \(\mathrm{Na}\) and \(\mathrm{Na}_{3} \mathrm{N}\)
