    A)            \[N>Z\]                                  

    B)            \[N=Z\]

    C)            \[N<Z\]                                  

    D)            \[N\ge Z\]

    Correct Answer: D

    Solution :

               For stability in case of lighter nuclei \[\frac{N}{Z}=1\] and for heavier nuclei \[\frac{N}{Z}>1\].
