    \[S{{N}^{2}}\]mechanism is involed in the following substitution:

    A) \[C{{H}_{1}}-C{{H}_{2}}-Cl+O{{H}^{-}}\]

    B) \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}-O{{H}^{-}}\]

    C) \[C{{H}_{3}}-\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}+O{{H}^{-}}\]

    D) \[C{{H}_{3}}-C{{H}_{2}}-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}+O{{H}^{-}}\]
