What is the meaning of encapsulation in Object Oriented Programming?
Show Hint
Encapsulation is like a capsule for medicine. The plastic shell (the class) bundles the medicine (the data) and protects it from the outside world. You interact with it through a controlled interface (by swallowing it), not by directly touching the raw ingredients.

- Avoiding class usage
- Using only public methods
- Allowing global access to variables
- Hiding implementation details

The Correct Option is D
Solution and Explanation
Encapsulation is one of the fundamental principles of Object-Oriented Programming (OOP). It refers to two related but distinct concepts:
1. Bundling: Grouping together the data (attributes) and the methods (functions) that operate on that data into a single unit, which is called a class. 2. Data Hiding: Restricting direct access to some of an object's components. This is typically achieved by making the data members `private` and providing `public` methods (getters and setters) to access or modify the data in a controlled way.
This data hiding aspect is a crucial part of encapsulation. It protects an object's internal state from outside interference and misuse. By hiding the implementation details and exposing only a well-defined public interface, the class becomes easier to use and maintain.
Therefore, "Hiding implementation details" is the best description of the meaning of encapsulation among the given choices.
