Question $4(1$ point$)$

Consider a spherical Gaussian surface of radius $R$ centered at the origin. A charge $Q$ is placed inside the sphere. To maximize the magnitude of the flux of the electric field through the Gaussian surface, the charge should be located

The charge can be located anywhere, since flux does not depend on the position of the charge as long as it is inside the sphere.
