Generalizations in UML Class Diagrams show that one class (subclass) inherits from another class (superclass). They are illustrated with a solid line with a hollow arrowhead pointing from the subclass to the superclass. Option A is incorrect because double dashed lines are used to represent dependencies between classes. Option C is incorrect because extending use cases through normalization is a process used in use case modeling, not in UML class modeling. Option D is incorrect because actors in UML class diagrams are represented as stick figures with the name of the actor next to it.
