From the given graph (graph 1), we see that the electric potential is a constant inside the sphere (V=constant) and decreases as 1/r outside the sphere. Thus, the electric field inside the sphere is zero and outside the sphere is proportional to 1/r. This behavior is shown in graph D, which represents the electric field as a function of distance. Therefore, choice D is the correct answer.
