    The number of\[\beta -\]particles emitted during the transformation of \[_{y}^{x}A\]to \[_{n}^{m}B.\]

    A) \[n+\frac{x-m}{2}+y\]                     

    B) \[\frac{x-m}{4}\]

    C) \[2y-n+x-m\]  

    D) \[n+\frac{x-m}{4}-y\]   

    Correct Answer: D

    Solution :

    \[_{y}^{x}A\to _{n}^{m}B+{{a}_{2}}{{\alpha }^{4}}+{{b}_{-1}}{{\beta }^{0}}\] \[x=m+4a\frac{x-m}{4}=a\] \[y=n+2\times a-b\] \[b=(n-y)+2a\] \[b=(n-y)+\frac{2}{4}(x-m)\] \[=n+\frac{x-m}{4}-y\] Hence, the correct option is [d].
