(D) When sodium $(Na)$ metal is dissolved in liquid ammonia $(NH_3)$, it undergoes ionization to form ammoniated cations and ammoniated electrons: $Na + (x+y)NH_3 \rightarrow [Na(NH_3)_x]^+ + [e(NH_3)_y]^-$ The blue colour of the solution is due to the excitation of the ammoniated electrons $[e(NH_3)_y]^-$ to higher energy levels, which absorb light in the visible region.

When sodium $(Na)$ metal is dissolved in liquid ammonia $(NH_3)$, it imparts a blue colour to the solution. This blue coloration is due to:
