The relation between the speed of light, permeability and permittivity

1.	The relation between the speed of light, permeability and permittivity is(a) C = 1/√(με)(b) C = με(c) C = μ/ε(d) C = 1/μεI got this question during an interview.Question is taken from Plane Waves in Dielectrics topic in chapter EM Wave Propagation of Electromagnetic Theory
Answer» Right choice is (a) C = 1/√(με) For EXPLANATION I would say: The STANDARD relation between SPEED of light, PERMEABILITY and PERMITTIVITY is given by c = 1/√(με). The value in air medium is 3 x 10^8 m/s.
