    A) \[{{C}_{6}}{{H}_{5}}\overset{+}{\mathop{C}}\,H{{C}_{6}}{{H}_{5}}\]

    B) \[{{C}_{6}}{{H}_{5}}\overset{+}{\mathop{C}}\,{{H}_{2}}\]

    C) \[C{{H}_{3}}\overset{+}{\mathop{C}}\,{{H}_{2}}\]

    D) \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}\overset{+}{\mathop{C}}\,{{H}_{2}}\]

    Correct Answer: A

    Solution :

      \[{{C}_{6}}{{H}_{5}}\overset{+\,\,\,\,}{\mathop{CH}}\,\,{{C}_{6}}{{H}_{5}}\] is the most stable carbonium ion due to resonance.
