Which of the following is an example of inheritance in OOP?

Inheritance is a mechanism in OOP that allows a new class to inherit the properties and methods of an existing class. This promotes code reusability and establishes a natural hierarchy between classes. In the given example, the Manager class inherits attributes such as name and salary from the Employee class, which means it can use or override these attributes while also introducing its own specific functionalities. This relationship facilitates the organization of code and helps to maintain a clear structure in complex systems. Inheritance can be single or multiple and plays a crucial role in the creation of polymorphic behavior. Option A is partially correct in that it indicates method sharing, but it does not illustrate inheritance specifically. Option B is incorrect because it describes a method in a standalone class without inheritance involved. Option D describes message passing, a communication mechanism, but does not relate to inheritance. Option E mentions a method associated with a class, which does not demonstrate inheritance.
