In Agile, backlog refinement and prioritization are continuous and collaborative activities. If user stories (especially those fixing demo issues) are left unprioritized, the team and product owner must work together to reassess and reorder the backlog for upcoming sprints. Option B is the most proactive, aligned with Agile practices, and focused on collaboration. Option A may help scope understanding but doesn't address prioritization. Option C misuses "spikes" (intended for research, not unplanned work). Option D is reactive and extends scope rather than adjusting priorities.
