There are four medium in which light is traveling. The speed of light in each medium along with relative permeability of the medium are given as below. Arrange the relative permittivity of each of the medium in increasing order.

(A) for Medium I, $V_I = 2 × 10^8\, m/s, μ_r=1$
(B) for Medium II, $V_{II} = 1.5 × 10^8\, m/s, μ_r=1$
(C) for Medium III, $V_{III} = 3 × 10^8\, m/s, μ_r=1$
(D) for Medium IV, $V_{IV}= 2 × 10^8\, m/s, μ_r=2$

Choose the correct answer from the options given below:

(C), (D), (A), (B)

The correct answer is Option (3) → (C), (D), (A), (B)

(C) for Medium III, $V_{III} = 3 × 10^8\, m/s, μ_r=1$
(D) for Medium IV, $V_{IV}= 2 × 10^8\, m/s, μ_r=2$
(A) for Medium I, $V_I = 2 × 10^8\, m/s, μ_r=1$
(B) for Medium II, $V_{II} = 1.5 × 10^8\, m/s, μ_r=1$
