In object-oriented approach, program consists ofinterrelated classes of objects.
Correct Answer: A
In object-oriented approach, a program is composed of classes and objects that interact with each other through messages. A class is a blueprint that defines the attributes and behaviors of a group of similar objects.
An object is an instance of a class that has its own state and canperform actions defined by the class. Objects can be related to each other through different types of relationships, such as inheritance, association, aggregation, and composition. Object-oriented approach aims to model the real-world entities and problems in terms of objects and their interactions, making the program more modular, reusable, and maintainable.
