Given the code fragment:
Map<Integer, String> books = new TreeMap<>();
books.put (1007, “A”);
books.put (1002, “C”);
books.put (1001, “B”);
books.put (1003, “B”);
System.out.println (books);
What is the result?
A. {1007 = A, 1002 = C, 1001 = B, 1003 = B}
B. {1001 = B, 1002 = C, 1003 = B, 1007 = A}
C. {1002 = C, 1003 = B, 1007 = A}
D. {1007 = A, 1001 = B, 1003 = B, 1002 = C}
