\[{{\mu }_{0}}\]denotes absolute permeability and \[{{E}_{0}}\]denotes the absolute permittivity of free space. Then the velocity of electromagnetic waves in free space is:

A)  \[{{\mu }_{0}}{{\varepsilon }_{0}}\]                                       

B)  \[\sqrt{{{\mu }_{0}}/{{\varepsilon }_{0}}}\]                        

C)  \[\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}\]          

D)         \[{{\varepsilon }_{0}}/{{\mu }_{0}}\]

E)  \[1/\sqrt{{{\mu }_{0}}/{{\varepsilon }_{0}}}\]
