What to choose if option for my separation from work isn't available filing for unemployment?

I’m trying to file for unemployment and I’m on the part asking why I was separated. I was laid off due to my position being eliminated, but here were the options:
Disciplinary Layoff (I wasn’t disciplined…so I don’t want to put that)
Lack of work
Leave of Absence
Mutual Agreement
Quit
Retirement
Still Employed
Strike/Lockout (Labor dispute)
Voluntary separation/buy out
Wrong employer/plant

Which do I choose??? Thanks. I’ve never filed before.
