0Consider three different closed surfaces. Surface \( A \) is a sphere of radius \( R \), surface \( B \) is a sphere of radius \( 2 R \), and surface \( C \) is a cube with side length \( R \). At the geometric center of each surface is a small ball carrying a positive charge \( +Q ; \) each ball is completely enclosed by the surface. Assuming that there are no other charged objects inside any of the surfaces, rank the surfaces based on the field line flux through them, from largest to smallest.
(A) \( \mathrm{A}\mathrm{B}\mathrm{C} \)
(B) \( \mathrm{A}\mathrm{C}\mathrm{B} \)
(C) \( \mathrm{B}\mathrm{C}\mathrm{A} \)
(D) All are equal
