The electromagnetic radiations are caused by (a) a stationary charge (b) uniformly moving charges (c) accelerated charges (d) all of the above

Answer: (c). Radiation needs time-varying fields that detach from the source. Stationary and uniformly moving charges give no such fields; only accelerated charges radiate. So the answer is (c) accelerated charges.
