Inheritance allows for the use of existing functionality of a base class in a derived class (1), the ability to override existing functionality in the derived class (2), and the implementation of new functionality in the derived class (3). It is also the basis for polymorphic behavior (4), but polymorphism is not explicitly mentioned in the options as facilitated by inheritance in the given choices. Containership (5) refers to a class containing objects of another class, which is not directly facilitated by inheritance but rather by composition.
