Answer:
[tex]\boxed{\text{donate electrons}}[/tex]
Explanation:
An atom with one to three valence electrons would have to gain seven to five valence electrons, respectively to get a stable octet.
It is easier for it to donate electrons and expose the stable octet of electrons in the shell below..
(A) is wrong. You can't move electrons to a lower shell, because it's already full.
(B) is wrong. The atom will donate electrons.
(C) is wrong. Moving electrons to a higher shell will make the atom more unstable.
