What does method overriding allow in terms of class relationships?

• A. Changing the signature of a method
• B. Defining a new method entirely
• C. Implementing the same method from a superclass in a subclass
• D. Using completely different names for methods in subclasses

Answer: (C)

Method overriding plays a crucial role in class relationships within object-oriented programming. It allows a subclass to provide a specific implementation of a method that is already defined in its superclass. This means that the method in the subclass has the same name, return type, and parameters as the method in the superclass, thereby allowing the subclass to modify or extend the behavior of that method.

This mechanism is fundamental to achieving polymorphism, which enables the application of the same method call on objects of different classes. When a method is called on an object of the subclass, the overridden version in the subclass is executed, even if the reference to the object is of the superclass type. This provides flexibility and enhances code reusability, as it allows the subclass to tailor the inherited behavior to its specific needs.

The other choices do not accurately describe method overriding. Changing the signature of a method refers to modifying aspects such as the method name or parameters, which does not align with the concept of overriding. Defining a new method entirely does not reflect overriding, as it implies creating a method that does not exist in the superclass. Lastly, using completely different names for methods in subclasses also falls outside of the concept of overriding, as it deviates from the requirement that the method names must
