Consider the following code segment: ArrayList nums = new ArrayList ();
nums. add(10);
nums. add(20);
nums. add(30);
nums. add(40);
nums. add(50);
int x = nums. remove(3);
int y = x + nums. remove(0);
int z = x + y;
nums. add(2, z);
Which of the following represents the value of nums after the code segment has been executed?

[20, 40, 90, 50]

[10, 20, 30, 40, 50]

[20, 30, 90, 50]

[20, 40, 50, 90]

[20, 30, 80, 50]
