Best answer
Right choice is (c) Zero

The explanation is: Gauss’s law indicates that there are no sources or sinks of the magnetic field inside a closed surface. A “closed surface” is a surface that completely encloses a volume with no holes. Therefore, the net magnetic flux through a closed surface is zero.
