What does encapsulation conceal in a class?

Only public members
Only private members
Both the interface and the implementation details
Only the implementation details

The correct answer is: Only the implementation details

Encapsulation is the process of bundling data and the methods that operate on them within a class. This allows for the data to be hidden from other parts of the program, protecting it from being accidentally modified or accessed by external code. In this context, encapsulation conceals only the implementation details of a class, not just the private members. Option A and B are incorrect because they do not encompass the full extent of what encapsulation conceals. Option C is incorrect because it states that encapsulation conceals both the interface and implementation details, when in fact it only hides the implementation details.
