Consider three different closed surfaces...

Consider three different closed surfaces, Surface A is a sphere of radius R, Surface B is a sphere of radius 2R, and surface C is a cube with side length R. At the geometric center of each closed surface is a small ball that is completely enclosed by the surface and carries electrical charge +q. 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.
