The correct answer is Control chart.

A Control chart visualizes cycle time and lead time and shows the distribution of how long issues take to move through the workflow. It is designed to show how long a single issue or a group of issues has been sitting in a given status and to highlight variation and outliers that indicate delays.

The Velocity chart reports completed work per sprint and helps with forecasting future sprint capacity. It does not measure how long issues sit in a particular status.

The Issue age report shows how long issues have been open or unresolved since creation or since they entered a board. It does not provide the per-status time distribution and cycle time detail that a control chart provides.

The Cumulative flow diagram shows the count of issues in each status over time to reveal bottlenecks and workflow stability. It does not display the time each issue spends in a given status or the distribution of those times.

The Burndown chart tracks remaining work in a sprint or release and is focused on scope and progress rather than the amount of time issues spend in specific statuses.
