View answer and explanation
Correct option: C
E⃗×B⃗\vec{E} \times \vec{B}
Option C (E⃗×B⃗\vec{E} \times \vec{B}) is correct because the direction of propagation of an electromagnetic wave is perpendicular to both the electric and magnetic field vectors, and is given by the Poynting vector, which is proportional to E⃗×B⃗\vec{E} \times \vec{B}.
