a & c are correct. reason-on flux there is no effect when from a closed surface incoming lines of forces have way to go out i.e outgoing lines of forces are present . In fig. when we draw lines of force from a & c they will intersect the curve at two points i.e. incoming & outgoing lines of forces are present i.e. no effect on flux ultimately. while when we draw line from b & d  they will intersect curve at one point i.e. incoming lines of forces are present but outgoing lines of forces are absent means tht affects flux.
