If \( \mathbf{E} \) and \( \mathbf{B} \) represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of electromagnetic
\( \mathrm{P} \) wave is along

W
(a) \( \mathbf{E} \).
(b) \( \mathbf{B} \).
(c) \( \mathbf{B} \times \mathbf{E} \).
(d) \( \mathbf{E} \times \mathbf{B} \).
