Who is accountable for managing the progress ot work during a Sprint?

According to the Scrum Guide, the Developers are accountable for managing the progress of work during a Sprint, as they are responsible for creating a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they imply that the Product Owner, the Scrum Master, or the most junior member of the team are accountable for managing the progress of work, which is not consistent with Scrum.
