Speed of EM wave in free space is given by (where symbols have their usual meaning)

View answer and explanation

Correct option: C

c=\frac{1}{\sqrt{\mu_0 \varepsilon_0}}

Option C,

c=\frac{1}{\sqrt{\mu_0 \varepsilon_0}}

, is correct because it is the standard formula for the speed of electromagnetic waves in free space.
