Consider this UML diagram and select all correct answers: A B 1,3,5 C id D If A is deleted, corresponding B objects are also deleted via existence dependency. If B is deleted, corresponding C objects are also deleted via existence dependency. A aggregates 1 or more B, B composes 1, 3, or 5 C objects. C is related to D via a qualification, where the key "id" is used to find a D instance.

Consider a vehicle purchasing software system that allows a customer to buy cars, buy motorbikes, and buy trucks. As all of the above are vehicles, there is a fourth functionality called buy vehicles whose purpose is to provide all the common functions in buying any type of vehicles. This last functionality, i.e. functionality (iv), is performed automatically by the software system and does not require any interaction with the customer. Draw the Use-Case diagram, including all actors and the relationships between all use cases. Suppose that the above vehicle purchasing software system has objects of the following classes: Vehicle this is an abstract class with all the common attributes and operations of the different types of vehicles.
