Asked in JEE Main 18th March 2nd Shift 2021 · Direction from E cross B, and oblique propagation
For travel along y, neither E nor B may have a y-component
That rules out every pair in (a), (b) and (d), each of which carries an E_y or a B_y
The surviving pair is (Eₓ, B_z) or (E_z, Bₓ): k̂ × ı̂ = ȷ̂ lies along the y-direction
