In the conversion of alkyne to trans-alkene by Birch reduction using alkali metals (such as `Na` or `K`) in liquid `NH_3` and alcohol (`MeOH` or `EtOH`),
`R - -= - R overset(Na +liq. NH_(3))underset(+EtOH)rarr`

the mechanism takes place in the formation of intermediate species in the following sequence:
A. (a) Radical anion `rarr` vinylic radical `rarr` trans-vinylic anion `rarr` trans-alkene
B. (b) Radical anion `rarr` trans-vinylic anion `rarr` vinylic radical `rarr` trans-alkene
C. (c) Vinylic radial `rarr` radical anion `rarr` trans-vinylic anion `rarr` trans-alkene
D. (d) Vinylic radical `rarr` trans-vinylic anion `rarr` radical anion `rarr` trans-alkene
