Quizplus · Accepted Answer

The method is intended to set the value of the model instance variable, so the correct choice is a setter method with a void return type and a parameter of type String to receive the new value. Option B is incorrect because it should return the current value of the model, not just retrieve it. Option C is almost correct, but it lacks the "set" part in the method name, indicating that it is a getter, not a setter. Option D has the correct parameter type, but it shouldn't return a value since it is just setting the value of an instance variable.
