    B)  \[CH{{I}_{3}}+6Ag+CH{{I}_{3}}\xrightarrow{\Delta }\]

    C) \[C{{H}_{3}}C{{H}_{2}}OH\underset{443{}^\circ C}{\mathop{\xrightarrow{\text{Conc}\text{. }{{H}_{2}}S{{O}_{4}}}}}\,\]

    D) \[B{{e}_{2}}C+{{H}_{2}}O\to \]

    Correct Answer: B

    Solution :

               Acetylene can be obtained by the reaction of silver and chloroform (or iodo form) \[2CH{{I}_{3}}+6Ag\xrightarrow{\Delta }\underset{\text{acetylene}}{\mathop{{{C}_{2}}{{H}_{2}}+6AgI}}\,\]
