it is released (emitted) as part of the electromagnetic spectrum.
When an electron returns to its ground state it emits energy in the form of light.
The energy may be emitted all at once or in smaller steps
The amount of energy that is absorbed is the same as the amount of energy that is released.
There is insufficient information in the question to properly answer it. You did not provide the list of "the following". In general, however, if it is the nucleus that returns to ground state, then gamma ray emission is the mechanism. It it is the electron cloud the returns to ground state, then x-ray emission is the mechanism. The end result is the same - a photon is emitted with a certain energy - only the mechanism differs.
It returns to the ground because of the effect of gravity.
it is released (emitted) as part of the electromagnetic spectrum.
An excited electron releases a photon as it returns to ground state.
When an electron returns to its ground state it emits energy in the form of light.
The energy may be emitted all at once or in smaller steps
A photon will be released!
The amount of energy that is absorbed is the same as the amount of energy that is released.

it gets absorbed by the ground
This is the energy needed to begin a chemical reaction.
popiseed muffins rock!
It is returned upward in the form of infrared light.
It gives off a photon of energy.
