What role does method overriding play in OOP?

Method overriding is a fundamental concept in object-oriented programming (OOP) that allows a subclass to provide a specific implementation for a method that is already defined in its superclass. This means that when a method in a subclass has the same name, return type, and parameters as a method in its superclass, the version of the method that is executed is the one defined in the subclass.

The significance of this is that it allows for dynamic polymorphism, where a single interface can be used to represent different underlying forms (data types). This is particularly useful in scenarios where a method needs to behave differently based on the object's class type, enhancing flexibility and reusability in code. By overriding methods, subclasses can customize or expand upon the base functionality provided by their superclasses without altering the original method's implementation in the superclass.

The other options pertain to different concepts in OOP. For instance, defining new methods within the same class does not involve overriding, as it refers to method declaration, not overriding an inherited method. The creation of multiple constructors relates to constructor overloading, which allows a class to have more than one constructor but does not involve method overriding. Lastly, combining two classes into one does not relate to overriding, as it suggests a merging
