How does an electromagnetic wave propagating through vacuum demonstrate both Faraday's Law of Induction and Ampère-Maxwell Law?
A.
A changing electric field produces direct current which then generates a steady magnetic field around it.
B.
An alternating current generates an alternating electric field but no accompanying electromagnetic waves are produced.
C.
A changing electric field induces a changing magnetic field and vice versa without needing any physical medium.
D.
A static electric field induces a static magnetic field resulting from displacement currents alone.
