    A) \[_{15}{{P}^{30}}\]

    B) \[_{14}S{{i}^{30}}\]

    C)  \[_{12}M{{g}^{24}}\]

    D)  \[_{56}B{{a}^{137}}\]

    Correct Answer: C

    Solution :

     \[{{\,}_{13}}A{{l}^{37}}+{{\,}_{0}}{{n}^{1}}\xrightarrow{{}}{{\,}_{12}}{{X}^{24}}+{{\,}_{1}}{{H}^{3}}\] \[{{\,}_{112}}N{{a}^{23}}+{{\,}_{1}}{{H}^{2}}\xrightarrow{{}}{{\,}_{12}}M{{g}^{24}}+{{\,}_{0}}{{n}^{1}}\]
