Aurorae are a result of the interaction of earth’s magnetosphere with

The correct choice is: “the solar wind”

The solar wind is a stream of charged particles (mainly electrons and protons) flowing from the Sun. When it interacts with the Earth's magnetosphere, charged particles are channelled along magnetic field lines towards the polar regions, where they collide with oxygen and nitrogen atoms in the upper atmosphere and make them glow. These glowing displays are the aurora borealis (northern lights) and aurora australis (southern lights).

The ozone layer, radio waves and the Moon's gravity play no part in producing aurorae.
