Question: A plane electromagnetic wave propagating along y-direction can have the following pair of electric field $(\overrightarrow{\mathrm{E}})$ and magnetic field $(\overrightarrow{\mathrm{B}})$
components.
$\mathrm{E}_{\mathrm{y}}, \mathrm{B}_{\mathrm{y}}$ or $\mathrm{E}_{\mathrm{z}}, \mathrm{B}_{\mathrm{z}}$
$\mathrm{E}_{\mathrm{y}}, \mathrm{B}_{\mathrm{x}}$ or $\mathrm{E}_{\mathrm{x}}, \mathrm{B}_{\mathrm{y}}$
$\mathrm{E}_{\mathrm{x}}, \mathrm{B}_{\mathrm{z}}$ or $\mathrm{E}_{z}, \mathrm{~B}_{\mathrm{x}}$
$E_{x}, B_{y}$ or $E_{y}, B_{x}$
