$(a)$ The electric lines of force entering into a Gaussian surface provide negative flux.
$(b)$ A charge ' $q$ ' is placed at the centre of a cube. The flux through all the faces will be the same.
$(c)$ In a uniform electric field net flux through a closed Gaussian surface containing no net charge, is zero.
$(d)$ When electric field is parallel to a Gaussian surface, it provides a finite non-zero flux.
