Hydrocarbons

The most suitable reagent for converting but-2-yne ( $H_{3} C - C \equiv C - C H_{3}$ ) into cis-2-butene is:

A.Na / liquid $N H_{3}$
B. $H_{2}$ , Pd/C, quinoline (Lindlar's catalyst)✓
C.Zn/HCl
D. $H g^{2 +} / H^{+}$ , $H_{2} O$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
