For a transparent medium, relative permeability and permittivity, \( \mu_r \) and \( \varepsilon_r \) are \( 1.0 \) and \( 1.44 \) respectively. The velocity of light in this medium would be,

1. A
   \( 4.32 \times 10^8\text{ m/s} \)
2. B
   \( 2.5 \times 10^8\text{ m/s} \)
3. C
   \( 3 \times 10^8\text{ m/s} \)
4. D
   \( 2.08 \times 10^8\text{ m/s} \)
