Answer to Question 1

D

Answer to Question 2

To reach its goal, a use case may need to call on the services of another independent use case, either because the latter already exists, or it qualifies as a full-fledged use case by itself and cannot be merged with the first one. This type of dependency is called an include relationship, and it allows a use case to remain concise and focused without relinquishing any of its function. The include dependency does not have the limitation of an extend relationship: it may be used conditionally or unconditionally, but it adds to the burden of maintenance, because changing one use case may affect many others.
