An ice cube has a bubble inside. When viewed from one side the apparent distance of the bubble is $$12$$ cm. When viewed from the opposite side, the apparent distance of the bubble is observed as $$4$$ cm. If the side of the ice cube is $$24$$ cm, the refractive index of the ice cube is

A

$$\frac{3}{2}$$

B

$$\frac{2}{3}$$

C

$$\frac{6}{5}$$

D

$$\frac{4}{3}$$
