OOP & Design Patterns - Encapsulation - Data Hiding, Getters/Setters & Access Modifiers

In which scenario is encapsulation most beneficial when designing a class?

AWhen you want to expose all internal data directly for easy access

BWhen you want to bundle data and methods while restricting direct access to internal state

CWhen you want to avoid using any access modifiers and rely on global variables

DWhen you want to implement multiple inheritance to reuse code

Step-by-Step Solution

Step 1: Understand encapsulation purpose
Encapsulation bundles data and methods and restricts direct access to internal state to protect object integrity.
Step 2: Analyze options
When you want to expose all internal data directly for easy access exposes internal data directly, violating encapsulation. When you want to avoid using any access modifiers and rely on global variables ignores access control, risking data corruption. When you want to implement multiple inheritance to reuse code relates to inheritance, not encapsulation.
Final Answer:
Option B -> Option B
Quick Check:
Encapsulation is about bundling and controlled access, not exposing all data or inheritance.

Quick Trick: Encapsulation bundles and hides, not exposes [OK]

Common Mistakes:

MISTAKES

Trap Explanation:

PITFALL

Options A and C seem simpler but break encapsulation principles; D is unrelated to encapsulation.
