Using instance method, complete the code to generate 'Alex Smith is a student in middle school.' as the output.

The correct choice effectively utilizes an instance method within a class context to generate the desired output, "Alex Smith is a student in middle school." In object-oriented programming, instance methods are defined to operate on individual instances of a class, allowing access to the attributes of a specific object.

In this case, the function definition starts with def print_name(self):, indicating that it's an instance method that can use self to reference the current object. Within the method, the formatted string utilizes the instance's first_name and last_name attributes to construct the output message. This is precisely what is needed to dynamically generate the correct sentence based on the object’s data.

For instance methods, it is essential that they accept self as a parameter, which represents the instance calling the method. This allows access to that instance’s attributes and methods. Since the output must change based on the specific instance's names, the use of instance attributes is crucial.

On the other hand, the other choices provided either incorrectly define the method or do not utilize instance attributes effectively. For example, some options may misuse the self parameter or specify arguments incorrectly, which would prevent the method from being called correctly on an instance of the class. Thus,
