An online stock trading system is under implementation. Which of the following events can be considered as a trigger for re-prioritization?

A team member leaving and being replaced is a resource management issue that may affect capacity but does not change the relative priority of requirements or solution components.

A new IPO on the stock market is an external business event that does not directly alter the priority ordering of implementation work items within the trading system project.

When new dependencies among solution components are discovered, the priority of those components must be reassessed to ensure dependent items are sequenced correctly before the items that rely on them. Dependencies directly constrain what can be built, integrated, or delivered and in what order, making them a legitimate and impactful trigger for re-prioritizing the work plan or backlog.

Growing quality defects signal a quality management concern requiring defect resolution activities, but they do not indicate that the relative priority of solution components needs to change.
