This threat is like a Rorschach test / we all tend to see what we each are predisposed to see. Perhaps the post sought benefit from the exercise more so than the answers.
Pmscc60 nailed it. Too many variables still undefined to reach a defendable selection/answer (unless many assumptions are made).
IMHO, maybe the most fundamental variable that needs to be defined is the anticipated impact velocity. That number will strongly influence so many of the other variables discussed here like distance, shot placement, shots thru cover, etc.
