$\varepsilon _ { 0 }$ Is Related to the Speed of Light and the Permeability

$\varepsilon _ { 0 }$ is related to the speed of light and the permeability of free space through the relation

A) $\varepsilon _ { 0 } = c ^ { 2 } \mu _ { 0 }$
B) $\varepsilon _ { 0 } = \frac { c ^ { 2 } } { \mu _ { 0 } }$
C) $\varepsilon _ { 0 } = \frac { 1 } { c ^ { 2 } \mu _ { 0 } }$
D) $\varepsilon _ { 0 } = \frac { \mu _ { 0 } } { c ^ { 2 } }$
