__________ provides information hiding in Object Oriented Programming.

• A. Inheritance
• B. Encapsulation
• C. Polymorphism
• D. Expressions

Answer: (B)

Encapsulation focuses on information hiding in Object-Oriented Programming. It keeps the internal state of an object private and only exposes a controlled interface of methods to interact with that state. This means external code can't directly access or modify the internal data, which protects integrity and reduces dependencies. For example, a class might store a balance as a private field and provide public methods to deposit or withdraw; callers use those methods, not direct access to the balance, so checks and rules are enforced consistently. Inheritance and polymorphism relate to how classes relate and how they behave through shared interfaces, but they do not primarily provide information hiding. Expressions are not a mechanism for hiding information in OOP.
