    The major product of the following reaction is:
    \[C{{H}_{3}}C{{H}_{2}}\underset{\begin{smallmatrix}  | \\  Br \end{smallmatrix}}{\mathop{CH}}\,-\underset{\begin{smallmatrix}  | \\  Br \end{smallmatrix}}{\mathop{C{{H}_{2}}}}\,\underset{in\,liq\,N{{H}_{3}}}{\mathop{\xrightarrow[(ii)\,NaN{{H}_{2}}]{(i)KOH\,alc.}}}\,\]

    A) \[C{{H}_{3}}CH=C=C{{H}_{2}}\]

    B) \[C{{H}_{3}}C{{H}_{2}}\underset{\underset{N{{H}_{2}}}{\mathop{|}}\,}{\mathop{CH}}\,-\underset{\underset{N{{H}_{2}}}{\mathop{|}}\,}{\mathop{CH}}\,{{ }_{2}}\]

    C) \[C{{H}_{3}}CH=CHC{{H}_{2}}N{{H}_{2}}\]

    D) \[C{{H}_{3}}C{{H}_{2}}C=CH\]
