Components of a Use Case Diagram:
  • Actor: Actors are external entities that interact with the system. They can be human users, other systems, or even hardware devices. Actors are represented by stick figures in a use case diagram.
  • Use Case: A use case represents a specific functionality or task that the system needs to perform. It describes a sequence of interactions between the system and an actor to achieve a specific goal. Use cases are represented by ovals in a use case diagram.
  • Relationship: Relationships show how actors interact with use cases in a use case diagram. There are several types of relationships, such as association, generalization, and include/extend. Relationships are represented by lines connecting actors and use cases.


Explanation:
The correct answer is Class which is not a component of a Use Case Diagram. Classes are part of a Class Diagram in UML, which is used to represent the structure of a system in terms of classes, attributes, and methods. Use Case Diagrams, on the other hand, focus on the functionalities of a system and how actors interact with those functionalities.
