    B)  A and B both are same optically active retention product

    C)  A and B both are optically inactive

    D)  A is optically inactive and B is retention product

    Correct Answer: A

    Solution :

    \[{{C}_{6}}{{H}_{5}}-CH=CH-\overset{+}{\mathop{C}}\,H-C{{H}_{3}}\xrightarrow[{}]{{}}\] \[{{C}_{6}}{{H}_{5}}CH=CH\underset{(\pm )}{\mathop{\underset{\text{racemic}\,\text{mixture}}{\mathop{-\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{OH} \end{smallmatrix}}{\mathop{\text{CH}}}\,-C{{H}_{3}}}}\,}}\,\]  (-OH gets added from both sides)
