B,C,D are correct. when alkali metals are dissolved in solvent they really released electron. when Na metal is dissolved in liquid NH3 then solution becomes blue in colour and readily releases e- . Na(s) +(x+y)NH3(l) = Na(NH3)x+(aq)+ e-(NH3)y(aq) blue
Electrons are highly reducing agent in nature due to their small and high energy. Electrons are paramagnetic and conduct electricity.

Alkali metals dissolve in liquid ammonia giving deep blue solutions which are conducting in nature. The blue colour of the solution is due to ammoniated electrons which absorb energy in the visible region of light.
