Correct Answer: BThe key concern for a Scrum Master in this situation is ensuring that the Development Teams can solve problems themselves and produce integrated Increments. This aligns with the principles of Agile and Scrum, which emphasize team self-sufficiency and collaboration. Ensuring that the teams build their capacity to handle challenges and work together to create integrated Increments is crucial for long-term success. Options like having enough work for team members, maintaining consistent velocity, or hiring additional resources may address immediate concerns but do not promote the development of a self-managing team.
