(B) The reduction of internal alkynes to $trans-$alkenes is achieved using alkali metals (like $Li$ or $Na$) in liquid ammonia $(NH_3)$.This is known as Birch reduction or dissolving metal reduction.$CH_3-C \equiv C-CH_2-CH_2-CH_3 \xrightarrow{Li/NH_3} 	ext{trans-}2	ext{-hexene}$.$Pt/H_2$ and $Pd/BaSO_4$ (Lindlar catalyst) typically result in the formation of $cis-$alkenes or complete reduction to alkanes.
