When the Scrum Team does not understand the goal, scope, or product domain, theScrum Master should facilitate a discussion between the Stakeholders, Product Owner, and Developers. This ensures clarity and shared understanding, enabling the team to move forward effectively.

According to the2020 Scrum Guide, the Scrum Master serves the team by:

Facilitating stakeholder collaborationas needed.

Ensuring that the Product Backlog is understoodby the Scrum Team.

Removing any barriers that hinder the team's ability to achieve the Sprint Goal.

Why the other options are incorrect:

A. Direct the Developers to stop working until the Product Owner improves the acceptance criteria:Stopping work is not productive, and collaboration with the Product Owner and stakeholders is the proper approach to resolving misunderstandings.

B. Cancel the Sprint and schedule a new Planning meeting:Cancelling the Sprint should be an absolute last resort and is typically done only when the Sprint Goal becomes unachievable.

C. Do nothing because this is the responsibility of the Product Owner:While the Product Owner owns the Product Backlog, the Scrum Master is responsible for facilitating collaboration and resolving impediments.
