Out of the following options which one can be used to produce a propagating electromagnetic wave?
Only accelerated charges radiate EM waves.
A stationary charge produces only an electric field, not a magnetic field.
A chargeless particle produces neither an electric nor a magnetic field.
An accelerating charge produces both an electric field and a time-varying magnetic field, which varies with space, leading to generation of an EM wave.
A charge moving at constant velocity produces only constant electric and magnetic fields, so it cannot produce an electromagnetic wave.
