    A) 16                          

    B) 4     

    C) 3                                             

    D) 14

    Correct Answer: C

    Solution :

    There are \[\text{16 }\!\!\pi\!\!\text{ -}\]electrons in the molecule, but this can not be aromatic by Huckel rule, so in order to be aromatic and to follow Huckel rule, only \[\text{14 }\!\!\pi\!\!\text{ -}\]electrons should be involved in making the ring.
