D) none of the above

Inheritance indicates an "is-a" relationship between classes, meaning that the subclass is a type of the superclass. For example, a Dog class would be a subclass of the Animal class, indicating that a dog is a type of animal. "Has-a" relationship refers to composition which is different from inheritance.
