Identify the correct statements with regard to the application of Gauss's law in electrostatics. (A) Gauss's law is true only for spherical closed surfaces. (B) The Gaussian surface should not pass through any discrete charges. (C) The total electric flux through any closed surface is zero, if no charge is enclosed by the surface. (D) The charge in the vicinity of the surface must be zero. Choose the correct answer from the options given below:

Two point charges \(8\,\mu C\) and \(-2\,\mu C\) are located at \(x = 2\,\text{cm}\) and \(x = 4\,\text{cm}\), respectively on the \(x\)-axis. The ratio of electric flux due to these charges through two spheres of radii \(3\,\text{cm}\) and \(5\,\text{cm}\) with their centers at the origin is ________.

What is the unit of electric flux in terms of the base units of SI?
