Which statement is correct when developers are working in the middle of a Sprint?

When developers are working in the middle of a Sprint, the statement that the scope may be clarified as more is learned is accurate. In Scrum, the Sprint is a time-boxed period where the team focuses on delivering a potentially releasable product increment. As the team works through the Sprint, they gain a better understanding of the work required and may discover new information that affects the scope of the Sprint Backlog. This process allows for adaptation and refinement, ensuring that the team can address evolving requirements or fix unforeseen issues.

The ability to clarify scope stems from the iterative and incremental nature of Scrum, which emphasizes learning and adaptation. This means that while the overall goal and the Sprint Backlog are defined at the beginning of the Sprint, developers can have discussions with the Product Owner to refine or clarify items as they progress, always within the framework of the current Sprint’s objectives.

In contrast, freezing the Sprint Backlog would impede the team's ability to be responsive and adaptive, and stating that no user acceptance tests could be conducted until the end of the Sprint limits opportunities for feedback and early validation. Additionally, indicating that work remaining cannot be updated until the next Sprint misrepresents the continuous progress tracking that occurs throughout the Sprint, as teams are encouraged to update
