In Java, a programmer should not use conditional operators to compare objects for equality. Instead, the equals() method should be used. Therefore choice c is correct, and choices a and d are incorrect. The compareTo() method does not evaluate to a boolean, so choice b will not compile. There is no operator in Java that is represented by ===, so choice e is incorrect.
