View answer and explanation

Correct option: A

the energy of the electron in the atom is lower than the energy of a free electron at rest

Option A (the energy of the electron in the atom is lower than the energy of a free electron at rest) is correct because the negative sign indicates that the electron is in a bound state, requiring energy to be removed from the atom.
