Which of the following region is the most 'energy deficit' region in terms of latitudinal heat balance ?

In the global latitudinal heat balance, there is a net radiation surplus between $38^\circ\text{ N}$ and $38^\circ\text{ S}$ and a net energy deficit poleward of $38^\circ$, with the maximum energy deficit occurring in the extreme polar zones between $80^\circ$ and $90^\circ$ latitudes in both hemispheres.
