Quizplus · Accepted Answer

A class at the bottom of the hierarchy should be a specialized or more specific type of the abstract class at the top. Therefore, it would not make sense for it to be a concrete or composite class, which would imply that it is not a specialized type of the abstract class. It also would not make sense for it to be an association as it is not a type of class.
