The intrinsic impedance is the ratio of square root of(a) Permittivity

1.	The intrinsic impedance is the ratio of square root of(a) Permittivity to permeability(b) Permeability to permittivity(c) Phase constant to wavelength(d) Wavelength to phase constantI got this question during an interview.I need to ask this question from Lossy and Lossless Dielectrics topic in section EM Wave Propagation of Electromagnetic Theory
Answer» Right CHOICE is (B) Permeability to permittivity To explain: The INTRINSIC IMPEDANCE is the impedance of a particular material. It is the ratio of square root of the permeability to permittivity. For air, the intrinsic impedance is 377 ohm or 120π.
