(C) The electric field $E$ due to a uniformly charged non-conducting solid sphere of radius $R$ is given by:$E = \begin{cases} \frac{1}{4 \pi \varepsilon_0} \cdot \frac{Q r}{R^3} ; & 	ext{for } r For $r For $r \geq R$,the electric field $E$ is inversely proportional to the square of the distance $r$ $(E \propto 1/r^2)$,which represents a hyperbolic curve.Thus,the graph starts from the origin,increases linearly until $r = R$,and then decreases following an inverse-square law for $r > R$.

In a uniformly charged sphere of total charge $Q$ and radius $R$,the electric field $E$ is plotted as a function of distance $r$ from the centre of the sphere. The graph which would correspond to the above description is:
