The electric and magnetic fields inside a waves are always perpendicular to each other. The direction of electromagnetic wave is always perpendicular to the plane that is contains the electric and magnetic field. Now in our case the wave is travelling to the right. That means the electric and magnetic field should be in a plane perpendicular to the right direction. That plane would be the plane of up direction and outward direction. SInce electric field is in outward direction, the magnetic field should be in the direction that is perpendicular to outward direction and is in the plane of outward and up direction. The only direction that satisfies these conditions is upward direction.
so magnetic field is in the up direction and the correct answer is option A
