x = 0; if (x1.hashCode() != x2.hashCode() ) x = x + 1; if (x3.equals(x4) ) x = x + 10; if (!x5.equals(x6) ) x = x + 100; if (x7.hashCode() == x8.hashCode() ) x = x + 1000; System.out.println("x = " + x); and assuming that the equals() and hashCode() methods are properly implemented, if the output is "x = 1111", which of the following statements will always be true?

• A. x2.equals(x1)
• B. x3.hashCode() == x4.hashCode()
• C. x5.hashCode() != x6.hashCode()
• D. x8.equals(x7)
