This is a very bad question: in theory, an atom's "outermost energy level" is when the electron associated with it is at an infinite distance. In practical terms, there is no such thing as "outermost energy level"; if enough energy is transferred to the electron, the electron will "jump" to a higher level. More energy means a higher energy level may be possible. The energy does have a limit: energies above the "work function" of a material will guarantee that the electron is completely free of the atom (see Einstein's famous photoelectric experiment).
Maybe your teacher means the outermost SHELL of the atom is filled, in which case, the atom has achieved a stable electron configuration.

An atom whose outermost energy level is filled doesn't want any extra electrons, and doesn't want to give any electrons away. That means it doesn't react; so, it would be stable, #3.

Stable you can also call it in noble gas state

3. Stable, although I would have said inert.
