A Sprint is a fixed-length, time-boxed event that ends when its duration expires, regardless of work completion. TheScrum Guidestates: "Sprints are the heartbeat of Scrum, where ideas are turned into value.
They are fixed length events of one month or less to create consistency." The end is determined by the time- box, not by acceptance, quality standards, or task completion.
* A:Product Owner acceptance occurs at Sprint Review, but doesn't define Sprint end.
* B:The Definition of "Done" applies to the Increment, not the Sprint's duration.
* C:Correct-the time-box dictates the end.
