(D) The nuclear reaction is given by: $_Y{A^X} \to {}_{Y-10}{B^{X-32}} + m({}_2He^4) + n({}_{-1}e^0)$.For mass number conservation: $X = (X - 32) + 4m$,which gives $4m = 32$,so $m = 8$.For atomic number conservation: $Y = (Y - 10) + 2m - n$. Substituting $m = 8$: $Y = Y - 10 + 16 - n$,which simplifies to $0 = 6 - n$,so $n = 6$.Therefore,the values of $m$ and $n$ are $8$ and $6$ respectively.
