Answer 4

Definition of Pareto optimal: An outcome is Pareto optimal if there is no other outcome that ALL players would prefer.

So, the (-5, -5) outcome is NOT Pareto optimal, because (-1, -1) is better for both players.
(-1, -1) IS Pareto optimal, because Player A would not prefer (-10, 0), Player B would not prefer (0, -10), and neither would prefer (-5, -5)

(-10, 0) IS Pareto optimal, because Player B would not prefer (0, -10) or (-1, -1), or (-5, -5).

(0, -10) IS Pareto optimal, because Player A would not prefer (-10, 0) or (-1, -1), or (-5, -5)... this was also from the internet, but i think it makes more sense;)
