- A. Aggregation
- B. Polymorphism
- C. Inheritance
- D. All of the mentioned

Polymorphism lets related objects respond to the same method name in different ways, usually through overridden methods in subclasses. Inheritance creates the class relationship, but polymorphism is the mechanism for differing implementations.
