Which of the following statements about access modifiers and encapsulation is INCORRECT?

AProtected members are accessible by any class in the same package regardless of inheritance

BPrivate members are accessible only within the defining class

CPublic members are accessible from any other class

DUsing private access modifier enforces data hiding

Step-by-Step Solution

Step 1: Recall access modifier rules
Private: class-only; Protected: subclass and package; Public: everywhere.
Step 2: Analyze Protected members are accessible by any class in the same package regardless of inheritance
Protected members are accessible within the same package and subclasses, but not by any class in the package regardless of inheritance.
Step 3: Validate other options
Options B, C, and D correctly describe access modifiers and encapsulation.
Final Answer:
Option A -> Option A
Quick Check:
Protected access is limited to subclasses and package, not all classes in package indiscriminately.

Quick Trick: Protected ≠ accessible by all classes in package, only subclasses and package [OK]
