When the incoming ray strikes the crystal face on the left, it refracts at the surface from air to ice along the path U1B0 in the direction shown in the figure. Then, it refracts again into air along the path B0S1 in the general direction shown in the figure. The correct outgoing ray is the ray that matches this path, and only option (C) matches this path.
