Which set of colours will come out in air for a situation shown in figure?

Angle of incidence is critical angle for green.
Now $\sin °\mathrm{C}=\frac{1}{\mu }\mu \propto \frac{1}{\lambda }$
So $\sin °C\propto \lambda$
Wavelengths for colours above green have critical angle more than the given angle, so they will be transmitted.
So yellow, orange and red have more wavelength than green, so they will came out in air.
