List list1 = Arrays.asList(10, 20);

List list2 = Arrays.asList(15, 30);

//line n1

Which code fragment, when inserted at line n1, prints 10 20 15 30?

Stream.of(list1, list2).flatMap(list -> list.stream()).forEach(s -> System.out.print(s + “ “));

Stream.of(list1, list2).flatMap(list -> list.intStream()).forEach(s -> System.out.print(s + “ “));

list1.stream().flatMap(list2.stream().flatMap(e1 -> e1.stream()).forEach(s -> System.out.println(s + “ “));

Stream.of(list1, list2).flatMapToInt(list -> list.stream()).forEach(s -> System.out.print(s + “ “));
