Zero permeability/permittivity implies which state?(a) No ions are all

1.	Zero permeability/permittivity implies which state?(a) No ions are allowed in the medium(b) No current is generated in the medium(c) No magnetic or electric energy is permitted in the medium(d) No resistivityI got this question during an online exam.Origin of the question is Plane Waves in Free Space in portion EM Wave Propagation of Electromagnetic Theory
Answer» Right answer is (c) No magnetic or ELECTRIC energy is permitted in the medium Best EXPLANATION: The ZERO PERMITTIVITY in an electric field refers to the ability of the field/medium to permit electric charges in it. SIMILARLY, zero permeability in a magnetic field refers to the ability of the field/medium to permit the magnetic energy into the field.
