Electromagnetic Waves

For a plane electromagnetic wave propagating in the $x$ -direction, which one of the following combinations gives the correct possible directions for the electric field ( $E$ ) and magnetic field ( $B$ ) respectively?

A. $\hat{j} + \hat{k}, \hat{j} + \hat{k}$
B. $- \hat{j} + \hat{k}, - \hat{j} - \hat{k}$ ✓
C. $\hat{j} + \hat{k}, - \hat{j} - \hat{k}$
D. $- \hat{j} + \hat{k}, - \hat{j} + \hat{k}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
