Why This Answer?
Static methods can be called on the class name (A) or on an instance (B). Instance methods need an object (C is valid). D tries to call an instance method on the class name (invalid).
Common Mistake
Watch Out!
Thinking static methods and instance methods are called the same way.
AP Exam Strategy
Static methods: ClassName.method(). Instance methods: object.method().
