Which of the following provides means for reading and/or modifying private attributes?

Choosing "a property" as the correct answer is valid because properties are designed in object-oriented programming to provide controlled access to private attributes of a class. They act as a bridge between the private fields and the outside world, allowing you to read or modify these private members safely.

Properties enable encapsulation, which is a fundamental principle of object-oriented design. Implementing properties generally involves defining accessors (getters) and mutators (setters) that specify how the private attributes can be accessed or updated. This allows for additional logic to be included when getting or setting values, such as validation checks or triggering events.

For example, if you have a private variable that should not be directly accessible, properties can provide a public method to get and set that variable’s value while keeping the variable itself private. This mechanism not only ensures data integrity but also hides implementation details, promoting clean and maintainable code.

In contrast, interfaces define the methods that a class must implement, constructors are special methods used to initialize objects, and fields are the raw data members of a class that don’t inherently provide methods to read or write their values. Therefore, while other options play vital roles in object-oriented programming, they do not specifically facilitate the structured access to private attributes as
