What happens when nitrogen fills its valence shell?

The choices can be found elsewhere and as follows:

A. Three electrons are lost, Creating N+3

B. Three electrons are lost, Creating N-3

C. Three electrons are gained, Creating N+3

D. Three electrons are gained, Creating N-3

I think the correct answer is option D. When nitrogen fills its valence shell then three electrons are gained, Creating N-3. Hope this answers the question.
