Given a method declared as public static List process(List nums) A programmer wants to use this method like this // INSERT DECLARATIONS HERE output = process(input); Which pairs of declarations could be placed at // INSERT DECLARATIONS HERE to allow the code to compile? (Choose all that apply.)

ArrayList<Integer> input = null; ArrayList<Integer> output = null;

ArrayList<Integer> input = null; List<Integer> output = null;

ArrayList<Integer> input = null; List<Number> output = null;

List<Number> input = null; ArrayList<Integer> output = null;

List<Number> input = null; List<Number> output = null;

List<Integer> input = null; List<Integer> output = null;
