Correct Answer: CWhen multiple agile teams work together, it is essential to maintain a balance between planned work and incoming requests. Directing the team to ignore all unplanned activities, as suggested in option D, could lead to communication breakdowns and inter-team conflicts. Instead, option C ensures that the team can maintain visibility and control of their workload by encouraging that unplanned requests be added to the iteration backlog. This approach supports transparency and effective prioritization, allowing the team to manage their capacity while addressing the legitimate needs of other teams.
