Greetings friend, would you kindly provide the answer that most accurately describes the above question of "what is a mutator." Thank you for kindly stopping and taking the time to answer my question.

What is a mutator? An instance method that modifies the object's internal state. An instance method that provides information about the state of an object, without modifying it. Code that interacts with another class or objects of that class. The parent class in an inheritance relationship. Hiding the implementation details of an object from the clients of the object, usually using the private keyword
