Pick up the correct statement about the solution of an alkali metal in liquid ammonia

The blue colour of the solution is due to ammoniated electronsSolutions of alkali metals in liq NH3 are good conductors of electricity,& the electrical conductivity of these solutions due to the movement of [flow of]  ammoniated ions as well as ammoniated electrons,and hence they are said to be mixed conductorsThe solution of alkali metals in liquid NH3 are paramagnetic,the paramagnetic nature of these solutions is due to presence of unpaired e-s [Ammoniated e-s]On long standing the solution, slowly liberates H2 with the formation of (sodmide) amideDue to the ammoniated e-s the solution is acting strong reducing agent.On increasing the concentration of solution, the blue colour changes to bronze colour and paramagnetic charater changes to diamagnetic i.e.,paramagnetism ↓es
