The correct answer is:
Electric field inside the uniformly charged sphere varies linearly, $E=\frac{k Q}{R^{3}} r,(r \leq R)$ while outside the sphere, it varies as inverse
square of distance, $E=\frac{k Q}{r^{2}} ;(r \geq R)$ which is correctly represented in option (c).
square of distance, $E=\frac{k Q}{r^{2}} ;(r \geq R)$ which is correctly represented in option (c).
