    In a given reaction\[_{Z}{{X}^{A}}\,\xrightarrow{{}}\,{{\,}_{Z+1}}{{Y}^{A}}\,\xrightarrow{{}}\,{{\,}_{Z-1}}{{K}^{A\,-\,4}}\,\xrightarrow{{}}{{\,}_{Z-1}}{{K}^{A-4}}\] Radioactive radiations are emitted in the sequence of

    A)  \[\alpha ,\,\,\beta ,\,\,\gamma \]              

    B)  \[\beta ,\,\,\alpha ,\,\,\gamma \]

    C)  \[\gamma ,\,\,\alpha ,\,\,\beta \]              

    D)  \[\gamma ,\,\,\beta ,\,\,\alpha \]

    Correct Answer: B

    Solution :

    As, atomic number increased by 1 indicates p-emission. Decreasing in mass number by 4 an atomic number by 2 indicates \[\alpha -emission\]. No change in mass number and atomic number indicates \[\gamma -emission\].
