$\hat{j} + \hat{k}, \hat{j} + \hat{k}$

$- \hat{j} + \hat{k}, - \hat{j} - \hat{k}$

$\hat{j} + \hat{k}, - \hat{j} - \hat{k}$

$- \hat{j} + \hat{k}, - \hat{j} + \hat{k}$

Explanation

To solve this problem, we need to understand the properties of electromagnetic waves. $\\$ For a plane electromagnetic wave propagating in the x-direction, the electric field $E \\$ and the magnetic field $B$ are perpendicular to each other and also to the direction of propagation. $\\$ Let's denote: $\\$ • The direction of propagation is $\hat{i}. \\$
