    A)                                                

    B)                       

    C)                                                                                      

    D)

    Solution :

                    Acceleration  due to gravity,  \[g\propto r(if\,r<{{R}_{E}})\]and\[g\propto \frac{1}{{{r}^{2}}}(if\,r>{{R}_{E}})\]
