When an electromagnetic wave enters an ionised layer of earth's atmosphere present in ionosphere
(a) the electron cloud will not oscillate in the electric field of the wave
(b) the electron cloud will oscillate in the electric field of wave in the phase of sinusoidal electromagnetic wave
(c) the electron cloud will oscillate in the electric field of wave in the opposite phase of sinusoidal electromagnetic wave
(d) the electron cloud will oscillate in the electric field of wave with a phase retardation of \( 90^{\circ} \) for a sinusoidal electromagnetic wave.
