A) Try your best to fight through the zombie horde, knowing the effort is futile. Result the zombies out number you and you get eaten alive.
B) Allow yourself to get bitten (in some way that doesn't allow the zombies in. Assume these zombies only eat humans, not each other). Result: you turn into a zombie but at least you won't die.
C) Shoot yourself with your last remaining bullet. Result: you die on your own terms and you won't be eaten alive
Which option do you pick and why?
