The correct Answer is ACE:

A - The objects CAN be reused C - Objects can share behaviors with other objects E - Object is the root class of all other objects

ACE is correct

ACE is correct as parent class methods need not be overriden in the child class, if parent class is not abstract or an interface

correct answer : A B: a subclass must override the methods from a superclass. This is an object-oriented feature because it allows developers to create a hierarchy of classes, where a subclass can inherit properties and behaviors from a superclass, and then override or extend those behaviors as needed. This is known as inheritance and polymorphism, which are fundamental object-oriented concepts. C not good : D E. Object is the root class of all other objects. This is not an object-oriented feature, as Object is a class in the Java programming language that is the superclass of all other classes. It provides a common set of methods that can be called on any object, such as equals(), hashCode(), and toString(). F.
