    In a fission reaction \[_{92}^{236}U{{\to }^{117}}X{{+}^{117}}Y+n+n\], the binding energy per nucleon of X and Y is 8.5 MeV whereas of \[^{236}U\]is 7.6 MeV. The total energy liberated will be about  

    A) 200 KeV

    B) 2 MeV

    C) 200 MeV

    D) 2000 MeV

    Correct Answer: C

    Solution :

    [c]\[\Delta E=8.5\times 234-7.6\times 236=195.4\ MeV=200\ MeV\].
