The property which is not of an electromagnetic wave travelling in free space is that :
Answer: (B) they originate from charges moving with uniform speed.
Electromagnetic waves are produced by accelerated charges. A charge moving with uniform velocity produces steady electric and magnetic fields but does not radiate.
The other statements are true: EM waves travel at $c = \dfrac{1}{\sqrt{\mu_0\epsilon_0}}$ in free space, they are transverse, and the average energy densities in the electric and magnetic fields are equal.
