(D) The conversion of an internal alkyne like $2$-hexyne into a $trans$-alkene is achieved by Birch reduction using an alkali metal (like $Li$ or $Na$) in liquid ammonia $(NH_3)$.This reaction proceeds via a $trans$-vinylic radical anion intermediate,which leads to the formation of the thermodynamically more stable $trans$-alkene product.
