    Which of the following will not lose asymmetry on reduction with \[LiAl{{H}_{4}}\] [Roorkee 2000]

    A) \[HO{{H}_{2}}C\begin{matrix}    \,\,\,CHO\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,  \\    +C{{H}_{2}}C{{H}_{3}}  \\    \,\,\,\,\,\,CH=C{{H}_{2}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,  \\ \end{matrix}\]

    B) \[{{H}_{2}}C=HCO\,\,\,+\,\,\,\begin{matrix}    \,\,\,\,C{{H}_{3}}\,\,\,\,\,\,\,  \\    \,\,\,\,\,\,\,\,\,CHO  \\    \,\,\,\,C{{H}_{2}}C{{H}_{3}}  \\ \end{matrix}\]

    C) \[HO{{H}_{2}}C+\begin{matrix}    C{{H}_{3}}\,\,\,\,\,\,  \\    \,\,\,\,\,\,\,\,\,COOH  \\    C\equiv CH\,\,\,  \\ \end{matrix}\]

    D) \[{{H}_{3}}C+\begin{matrix}    CHO\,\,\,\,\,\,\,\,  \\    \,\,\,\,\,\,\,\,\,\,\,C\equiv N  \\    C{{H}_{2}}N{{H}_{2}}  \\ \end{matrix}\]
