$\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}$
