Options

A. They all dissolve in liquid `NH_(3)`.
B. Dilute solutions of group 2 metals in liquid `NH_(3)` are bright blue in color but the concentrated solutions are bronze colored.
C. Solutions of group 2 metals in liquid `NH_(3)` decompose very slowly, forming amides and evolving `H_(2)`.
D. The evaporation of `NH_(3)` from the solutions of group 2 metals gives the metals.
