Suppose that an infinite planar slab centered on the $z=0$ plane carries a uniform current flowing in the $+x$ direction. Which mirrors below satisfy the mirror rule?
A) Any mirror parallel to the $z=0$ plane
B) Any mirror parallel to the $\boldsymbol{y}=\mathbf{0}$ plane
C) Any mirror parallel to the $x=0$ plane
D) Any mirror whose plane is perpendicular to the slab
E) None of the mirrors above satisfy the mirror rule.

The mirror rule is satisfied by a mirror parallel to the $y=0$ plane because it reflects the current direction correctly, maintaining the symmetry of the system.
