Artifacts that could be delivered at the end of a Sprint

Hi everybody,

One question about Scrum framework. It is from the PSM I exam.


Which of these may a Develpment Team deliver at the end of a Sprint (Choose 2):

A) An increment of software with minor bugs in it.

B) A single document, if that is what the Product Owner asked for

C) Failing unit tests, to identify acceptance tests for the next Sprint.

D) An increment of working software that is "done".


I exclude C). I think the correct anwer should be A) and D). But, why a single document could not be delivered if the Product Owner has asked for it?


Thank you in advance.
