Which statement best describes a sprint's time frame?

• A. A sprint is an independent unit of work
• B. A sprint is a fixed time window to complete a set of user stories
• C. A sprint is the entire project
• D. A sprint is only the testing phase

Answer: (B)

In Scrum, a sprint is a fixed-length iteration where the team works to deliver a potentially shippable product increment. The work chosen for the sprint comes from the product backlog as a set of user stories, forming the sprint backlog, and the team aims to complete that predefined set within the same duration each sprint (for example, two weeks). This fixed time window provides rhythm, predictability, and a clear goal for the iteration. The other statements don’t fit because a sprint is not just an independent unit of work, not the entire project, and not only the testing phase—the sprint covers all activities needed to produce the increment within that time box.
