$\begin {array} {1 1} (a)\text{Ampere’s law states that: flux of B through any closed surface is$\mu_0$times the current passing through the area bounded by closed surface.}\\ (b)\; \text{Gauss’s law for magnetic field in magneto statics serves the same purpose as Gauss’s law for electric field in electrostatics}. \\ (c)\; \text{Gauss’s law for magnetic field states that the flux of B through any closed surface is always zero, whether or not there are currents within the surface} \\ (d)\; \text{All of the above }\end {array}$

Ampere’s law states $B. dl = \mu_o\: l$….equivalent of gauss’s law for electric field in electrostatics. Gauss’s law for magnetic field states $B. dS = 0$
Ans : (d)
