From insolation, __% is reflected by atmospheric gases and dust

Explanation:
Insolation is the solar energy that reaches Earth. Some of that energy is reflected back into space by the atmosphere itself, due to scattering by gas molecules and by airborne dust and aerosols. This atmospheric reflection is relatively small, about 8% of the incoming radiation, which is why it’s the best match among the options. The vast majority of reflection in the Earth–atmosphere system comes from clouds and the surface, not the gases and dust in the air.
