Quizplus · Accepted Answer

Inheritance is the mechanism by which an object acquires the properties of another object of its parent class, and it is used for code reusability and creating a hierarchical relationship between the classes. The other options are incorrect. Objects possess attributes and instantiate classes (not instances), and operations can change object attributes or perform other actions without changing attributes.
