B
ammoniacal silver nitrate
44%
C
ammoniacal cuprous chloride

D
ethanolic potassium hydroxide
33%
Solution:
Isomerisation of $1 $ -butyne to $2$ -butyne can be achived by treatment with ethanolic $KOH$
$\underset{\text {1-butyne }}{H _{3} C- CH _{2}- C \equiv CH} \xrightarrow[KOH \text { (ethanolic) }]{\text { Isomerisation }}\underset{\text{2-butyne}}{C H_{3}-C \equiv C-C H_{3}}$
