B. \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}\overset{\begin{smallmatrix} O \\ \parallel \end{smallmatrix}}{\mathop{-C-}}\,CH=C{{H}_{2}}\]
C. \[{{C}_{6}}{{H}_{5}}\overset{\begin{smallmatrix} O \\ \parallel \end{smallmatrix}}{\mathop{-C-}}\,CH=CH-C{{H}_{3}}\]
D. \[{{C}_{6}}{{H}_{5}}-CH=CH\overset{\begin{smallmatrix} O \\ \parallel \end{smallmatrix}}{\mathop{-C-}}\,C{{H}_{3}}\]  
Answer :   \[{{C}_{6}}{{H}_{5}}-CH=CH\overset{\begin{smallmatrix} O \\ \parallel \end{smallmatrix}}{\mathop{-C-}}\,C{{H}_{3}}\]
