a.
Sequence diagram:
Sequence diagram is a tool that represents the way of interaction of objects to accomplish a work. The objects are labeled with the task to be performed. The arrows show the direction of communication. Objects are shown by rectangles.
Use case diagrams:
Use case diagram is a tool to represent the way of interaction of user with system. Rectangle is used to represent the system. Oval is used for interaction of user and system.
Class diagrams:
Class diagrams not only show associations between different classes but also reveal multiplicities of these associations. Classes are shown by rectangles. Here, relationships of classes are shown by lines.
