In which layer of the atmosphere the aurora is created?

In the Troposphere
In the Stratosphere
In the mesosphere
In the Thermosphere
Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost.
