"The most moral of the people" by making this distinction you are negating the statement,
"all humans have the same value." This is clearly an untrue statement, but it makes you feel warm inside doesn't it? Also who would decide who is the most 'moral' and what would the criteria be... volunteer hours? Now I would like to add a #4 to that list - those most likely to survive, with the greatest strength (in every sort of way) and most useful skills, especially teamwork.
I would then be stuck between choice 1 and 4... but I think #1 is the one, why? If a boat is sinking I don't think you would have time to fuss over who is most deserving of a place on a lifeboat.
