During a sprint, the product owner asks the scrum master to work on a quality issue as soon as possible. Which of the following is the scrum master's MOST likely action?

Submitting a change request to a Change Control Board is a practice from traditional waterfall project management and is not part of the Scrum framework applied during sprints.

Deferring work to the next sprint is a product owner decision about backlog prioritization and does not actively resolve an urgent quality issue the product owner has flagged.

One of the scrum master's core responsibilities is removing impediments that cannot be resolved at the team level, and escalating to upper management is the appropriate mechanism for organizational-level quality issues. The scrum master serves the organization by facilitating resolution of blockers that exceed the team's authority or resources. Escalating ensures the quality concern receives the organizational attention required without disrupting the sprint's protected work.

Simply informing the product owner of potential delays is a passive communication response and does not take action to address or resolve the quality issue as requested.
