Encapsulation is a principle of object-oriented programming that aims to hide the implementation details of a class from the outside world and provide a set of public methods to interact with the class. To achieve encapsulation, the class should provide a set of public methods to access and modify its private fields or attributes. The implementation details should be hidden from the outside world by using access modifiers such as private or protected. Therefore, option D is correct as it correctly states that encapsulation requires a set of public methods in the class to interact with it and hide the implementation details.
