(D) Aurora will shift towards lower latitudes Earth's magnetic reversal is not a momentary event, it occurs over a long duration of time. Reversal means first magnetic field will be weakening then become zero and then increasing in reverse direction. With reversal, since magnetic field will be weakening, the ions of solar winds which cause aurora on poles today will spread all over the globe. This will lead to interaction of atmospheric gases will high solar wind ions in lower latitudes as well i.e. the aurora will also form in lower latitude area of the globe.
