Given the code fragment: 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?

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

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

C. list1.stream() .flatMap(list.stream()).flatMap(e1 -> e1.stream()).forEach(s -> System.out.println(s + " "));

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