A non-conducting solid sphere of radius R is uniformly charged. The magnitude of electric field due to the sphere at a distance r from its centre :
(A) increases as r increases for r < R
(B) decreases as r increases for 0 < r < ∞
(C) decreases as r increases for R < r < ∞
(D) is discontinuous at r = R
(E) both (a) and (c) are correct
