In an electro magnetic wave, If $\vec B$ and $\vec E$ represents the magnetic field and electric field respectively. Then the direction of propagation of electromagnetic wave is along the direction of

$\vec B$ $\vec E$ $\vec E × \vec B$ $\vec B × \vec E$

$\vec E × \vec B$

The correct answer is Option (3) → $\vec E × \vec B$
