Sodium metal on dissolution in liquid ammonia gives a deep blue solution due to the formation of ammoniated electrons. The reaction is

represented as follows -

\mathrm{\mathrm{Na}+(x+y) \mathrm{NH}_3 \longrightarrow\left[\mathrm{Na}(\mathrm{NH})_x\right]^{+}+\underset{\textup{ammoniated electrons}}{\left[e\left(\mathrm{NH}_3\right)_y\right] }}

Hence option 4 is correct.
