    Question

    Which of the following best describes the concept of abstraction in object-oriented programming (OOP)? 

    A Abstraction is the process of bundling data and methods that operate on the data into a single unit, typically a class. Correct Answer Incorrect Answer
    B Abstraction refers to the hiding of internal implementation details and showing only the essential features of an object. Correct Answer Incorrect Answer
    C Abstraction is the process of creating multiple methods with the same name but different implementations. Correct Answer Incorrect Answer
    D Abstraction means ensuring that derived classes implement all methods declared in a base class. Correct Answer Incorrect Answer
    E Abstraction is a technique that allows an object to take on many forms depending on the context. Correct Answer Incorrect Answer

    Solution

    Abstraction in OOP is a fundamental concept that involves hiding the complex internal details of a system and exposing only what is necessary to the user. This simplifies the interaction with objects and promotes reusability, as the user can interact with high-level methods without needing to understand their internal workings. It allows developers to create complex systems while maintaining a clear and simplified interface. In practical terms, abstraction can be achieved through the use of abstract classes and interfaces, where only the essential behavior is defined, and the details are hidden. Why other options are wrong: A) This describes encapsulation, not abstraction, which involves combining data and methods into a class. C) This is method overloading, where multiple methods share the same name but differ in parameters or implementation. D) This refers to inheritance and polymorphism, not abstraction. E) This describes polymorphism, which allows objects to behave differently based on the context.
