Solution

The correct options are
B
Shows blue colour

C
Exhibits electrical conductivity

$N a + (x + y) N H_{3} ⟶ [N a (N H_{3})_{x}]^{+} + [e (N H_{3})_{y}]^{-}$

The emission spectrum of the solvated electrons $[e (N H_{3})_{y}]^{-}$ is blue!

Because of the solvated ions, the solution is conducting. Neither sodium amide nor hydrogen gas are produced.
