Analyze the following snippet. Which method should be distinguished as a static method?

The correct answer is A. The isElementCorrect() method should be static. The isElementCorrect() method does not use self or any instance attributes and only processes its input parameter, so it should be defined as a static method. The isSolved() method relies on the instance attribute self.progress and must remain an instance method.
