To override a method in a subclass, the method must be defined in the subclass using the same signature and compatible return type as the method in its parent class. B. Overloading a method means that there is more than one method with the same name but with different signatures to distinguish them. C. If two methods in the same class have the same name and the same arguments, but only differ in return type, a compiler error will be generated. D. A private method cannot be overridden. If a method defined in a subclass is private in its parent class, the two methods are completely unrelated.
