The incorrect statement about electromagnetic waves is C. induction of electric fields by changing magnetic fields only occurs if a conducting material is present.
Electromagnetic waves do not rely on any medium for propagation, which means that the generation of fields is irrespective of the presence of a conducting material. 

. C. Induction of electric fields by changing magnetic fields occurs only if a conducting material is present.  is correct
