This is College Physics Answers with Shaun Dychko. Polarization axis is along the direction of the electric field of the electromagnetic wave and an electric field is perpendicular to the direction of propagation. Because electromagnetic waves are considered transverse waves and that the thing that’s oscillating in this case electric and magnetic fields are perpendicular to the direction of propagation. So the answer is <i>B</i>.
