A glass block has a refractive index in air of n_g. The glass block is placed in two different liquids: liquid X with a refractive index of n_X and liquid Y with a refractive index of n_Y.

In liquid X $\frac{n_{g}}{n_{X}} = 2$ and in liquid Y $\frac{n_{g}}{n_{Y}} = 1.5 .$ What is $\frac{speed of light in liquid X}{speed of light in liquid Y}$ ?

A. $\frac{2}{4}$

B. $\frac{3}{4}$

C. $\frac{4}{3}$

D. $3$
