Liquid ammonia remains diamagnetic

(D) When sodium metal dissolves in liquid $NH_3$,it undergoes the following reaction: $Na + (x+y)NH_3 \rightarrow [Na(NH_3)_x]^+ + [e(NH_3)_y]^-$. The ammoniated electrons $[e(NH_3)_y]^-$ are responsible for the blue color,high electrical conductivity,and paramagnetic nature of the solution. Therefore,the solution becomes paramagnetic,not diamagnetic. Thus,option $D$ is the correct answer.
