All the facts given above are correct.

Vedclass · Answer

(D) Alkali metals dissolve in liquid $NH_3$ to form a deep blue solution.The blue colour is due to the presence of ammoniated (solvated) electrons,which absorb energy in the visible region of light.These dilute solutions are paramagnetic due to the presence of unpaired electrons.As the concentration increases,the solution turns bronze-coloured and becomes diamagnetic due to the pairing of electrons.Therefore,all the given statements are correct.
