Solution

The correct option is A they form hexammoniates , M(NH3)6
When an alkaline earth metals dissolve readily in liquid ammonia,to form solvated metal cations and solvated electrons which give a solution of deep blue colour.

Now, when the G-1 solutions evaporate, we get the metal back, but in the case of G-2 solutions (except Beryllium), they give a metal complex, [M(NH3)6][M(NHX3)X6].
