I'd have to day d. (I've worked in electronics for many years and never had to know anything about magnetic wave direction, only that the magnetic field and the electric field are at right angles....)

The answer actually depends on the boundary conditions, but for a wave in vacuum in free space the answer is b. The electric field is perpendicular to both the magnetic field and the wave direction.

It's b. Both the E field and the B field are perpendicular to the wave direction.
