    A)                 \[e,\,p,\,n,\,\alpha \]    

    B)                 \[n,\,p,\,e,\,\alpha \]

    C)                 \[n,\,p,\,\alpha ,e\]       

    D)                 \[n,\,\alpha ,\,p,\,e\]

    Correct Answer: D

    Solution :

               \[\frac{e}{m}\] for (i)  neutron  \[=\frac{0}{1}=0\] (ii) \[\alpha -\] particle  \[=\frac{2}{4}=0.5\] (iii) Proton \[=\frac{1}{1}=1\] (iv) electron \[=\frac{1}{1/1837}=1837\].
