Question

All alkali metals dissolve in anhydrous liquid ammonia to give blue colour 
solution. It is the ammoniated electron which is responsible for the blue colour
of the solution, and the electrical conductivity is due to the ammoniated 
cation, [M(NH3)x]+ as well as the ammoniated electron, -, values of x and y 
depend on the extent of solvation by NH3. Dilute solutions are paramagnetic due 
to free ammoniated electrons.

Correct answer: B. If conc. of solution is increased, then association of solvated electrons get started hence, paramagnetism decreases and solution changes to bronze colour.
